| Colloque - Valentin Wyart : The What?, How? And Why? Of Behavior: Using Cognitive Computational Models to Answer Distinct Questions about Human Cognition | 03 Oct 2025 | 00:18:22 | |
Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Theme: Human Singularity The What?, How? And Why? Of Behavior: Using Cognitive Computational Models to Answer Distinct Questions about Human Cognition Colloque - Valentin Wyart : The What?, How? And Why? Of Behavior: Using Cognitive Computational Models to Answer Distinct Questions about Human Cognition Valentin Wyart Résumé Quantitative modeling approaches are routinely used in cognitive science to make sense of behavior. Statistical models are designed to test *what* specific patterns are present in behavior, whereas cognitive computational models are developed to describe *how* specific behavioral patterns may emerge from latent cognitive processes. These two types of modeling approaches have successfully identified characteristic (and sometimes suboptimal) features of human learning and decision-making under uncertainty. In this talk, I will argue that cognitive computational models can be used to answer the distinct question of *why* these characteristic features are there. I will use recent studies that rely on different classes of models (low-dimensional algorithmic models, high-dimensional neural networks) to explain characteristic features of human cognition in terms of latent objectives and constraints. | |||
| Colloque - Mathias Sablé-Meyer : Dissecting the Language of Thought Hypothesis across Marr's Levels | 03 Oct 2025 | 00:17:56 | |
Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Theme: Human Singularity Dissecting the Language of Thought Hypothesis across Marr's Levels Colloque - Mathias Sablé-Meyer : Dissecting the Language of Thought Hypothesis across Marr's Levels Mathias Sablé-Meyer Résumé The Language of Thought (LoT) hypothesis posits that mental representations are best understood as programme-like objects; indeed, "thoughts" share properties such as productivity and systematicity with programming languages. I tackle questions that arise from taking this hypothesis at face value and unfolding its predictions, from computational accounts to mechanistic implementation. First, zooming on humans' cognition of geometric shapes, I show that in all human groups tested (adults, children, congenitally blind), the perception of shapes is heavily influenced by geometric features. Then, I show using MEG and fMRI that the neural signature of these exact geometric properties is separate both in timing and localisation from typical visual processes. To generalise beyond quadrilaterals, I commit to a proposition for a generative language of shapes to account for the complexity of geometric shapes in humans, while implementing an algorithm for perception-as-program-inference. Finally, building on recent results in rodent neuroscience, I sketch a research programme and give preliminary results on a mechanistic understanding of how program-like representations might be implemented by populations of neurons. | |||
| Colloque - Floris de Lange : Uniquely Human Prediction? | 03 Oct 2025 | 00:34:40 | |
Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Theme: Human Singularity Uniquely Human Prediction? Colloque - Floris de Lange : Uniquely Human Prediction? Floris de Lange Résumé The brain is fundamentally a predictive organ that uses internal models to extrapolate future events from current inputs. While this predictive capacity exists across species, what may be uniquely human are the specific internal models we employ. Using AI tools to quantify predictability in naturalistic environments, we can examine prediction at multiple levels of abstraction. In my talk I will highlight recent work from the domain of language, music and visual perception, elucidating how uniquely human experiences and capabilities shape our predictive models of the world. | |||

Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Theme: Neural Codes in Monkeys and Humans Do Monkeys See the Way We Do? Colloque - Arun SP : Do Monkeys See the Way We Do? Arun SP Résumé Monkeys are widely used as model organisms for vision and cognition. While their anatomy and physiology have strong correspondences with humans, it is unclear whether they truly see the way we do. In most studies, monkeys are extensively trained on specific tasks, leaving us without a more general answer to this question, along with the nagging doubt that the extensive training might have altered their perception. So how do we then test whether monkeys see the way we do? | |||
| Colloque - Lorenzo Ciccione : The Perception and Understanding of Patterns and Graphics | 03 Oct 2025 | 00:16:59 | |
Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Theme: Space, Time, and Number The Perception and Understanding of Patterns and Graphics Colloque - Lorenzo Ciccione : The Perception and Understanding of Patterns and Graphics Lorenzo Ciccione Résumé Graphics are a cultural product, meaning that they are a human invention with defined rules and syntax. In this respect, they are very similar to written words and numbers, probably the two most famous cultural inventions. However, unlike them, graphics have been invented much more recently and they became widespread only in the last two centuries. Furthermore, graphicacy—the ability to read and understand graphics—has received little attention from cognitive psychology. In this talk, I will present some findings about the human ability to intuitively extract statistics and mathematical relations from graphical representations. Specifically, I will show that: graphics' intuitions are available early on in development, independently from formal education, and correlate with statistical and mathematical knowledge; judging the trends of noisy graphical displays recycles brain areas usually devoted to the detection of objects' orientation (in agreement with the neuronal recycling hypothesis) and also activates the brain network for mathematics; both children and adults can extrapolate non-linear mathematical patterns, with the notable exception of quadratic and exponential functions. | |||

I will focus on the roles of slow cortical potentials and spontaneous ongoing brain activity as revealed by our recent empirical work. I will also discuss neural and computational mechanisms underpinning humans' remarkable one-shot learning capability in visual perception, as well as how lifelong prior knowledge influences conscious perception. | |||
| Colloque - Lucia Melloni : Building a Theory of Consciousness, One Collaboration at a Time | 02 Oct 2025 | 00:38:06 | |

Few frameworks have shaped this quest as deeply as Stanislas Dehaene's Global Neuronal Workspace Theory (GNWT). By proposing that conscious access arises through large-scale broadcasting and ignition across fronto-parietal networks, GNWT provided both a conceptual framework and concrete, testable predictions | |||
| Colloque - Jean-Pierre Changeux : The Global Neuronal Workspace from the Molecular to the Cognitive Level: Consequences for Pathology and Pharmacology | 02 Oct 2025 | 00:35:05 | |
Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Theme: Perception and Consciousness The Global Neuronal Workspace from the Molecular to the Cognitive Level: Consequences for Pathology and Pharmacology Colloque - Jean-Pierre Changeux : The Global Neuronal Workspace from the Molecular to the Cognitive Level: Consequences for Pathology and Pharmacology Jean-Pierre Changeux Résumé The global neuronal workspace (GNW) theory originates from decades-long productive dialogs between Dehaene & Changeux which aimed, in the late 80's, at the elaboration of formal neuronal networks of cognitive functions. They initially included birdsong learning by selection, the Wisconsin card sorting task, infants numerosity detection...All these models were grounded on a molecular level which included allosteric neurotransmitter receptors. In 1998, the "global neuronal workspace" was integrated into a formal organism in order to pass the effort-full, "conscious", Stroop task. It was postulated to consist of a brain-scale—multimodal & horizontal—network of widely distributed neurons with long axon neurons, distinct from modality-specific localized non-conscious processors, including neurons which included the prefontal, parieto-temporal, cingulate… areas. The access of an outside representation to the conscious workspace would manifest itself by an "ignition" of the workspace network. At this stage, an important number of imaging and electrophysiological data appear consistent with the GNW theory. In this contribution, emphasis shall be given to the bottomup contribution of the molecular level and its consequences for the understanding of neuropsychiatric diseases and rational drug design, in the larger context of a novel precision pharmacology. | |||

| Colloque - Véronique Izard : Why Is Conceptual Learning so Hard? | 02 Oct 2025 | 00:17:54 | |
Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Theme: Infancy, Development, and Education Why Is Conceptual Learning so Hard? Colloque - Véronique Izard : Why Is Conceptual Learning so Hard? Véronique Izard Résumé Learning concepts can be very difficult, especially in science and mathematics. For instance, children continue to struggle with fractions even after several years of formal instruction on the topic; and adults display persistent difficulties with algebra, biology or physics. Why these failures—and what happens during the long periods of time during which learners are struggling? While most theories of conceptual learning contend that learning proceeds gradually, little step by little step, I will present evidence showing that people experience sudden Eureka moments while learning mathematics. During these episodes, an insight suddenly breaks into consciousness, leading to a leap in understanding. These findings invite us to reconsider learning mechanisms in light of theories of conscious and unconscious processing. | |||
| Colloque - Lisa Feigenson : Developmental Origins of Human Curiosity | 02 Oct 2025 | 00:20:11 | |
Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Theme: Infancy, Development, and Education Developmental Origins of Human Curiosity Colloque - Lisa Feigenson : Developmental Origins of Human Curiosity Lisa Feigenson Résumé Curiosity underpins the greatest of human achievements, from exploring the reaches of our solar system to discovering the structure of our own minds. Where does this drive come from? Here I suggest that far from being reliant on language and sophisticated metacognitive skills, curiosity is present from our earliest days. In support of this claim, I discuss work showing that preverbal infants not only experience curiosity but harness it: when babies' predictions fail to accord with their observations, they look longer, learn more, and produce exploratory behaviors. Critically, their exploration is guided by a desire to explain—long before they have the words to describe what they see, babies seek to understand why things happen as they do. In this sense, the curiosity that emerges in infancy lays the foundation for a lifetime of discovery. | |||
| Colloque - Bruce McCandliss : Discovering Combinatorial Affordances of Elements to Form Gestalts: Learning to "See Ideas via Groupitizing and Visual Word Forms | 02 Oct 2025 | 00:36:34 | |
Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Theme: Infancy, Development, and Education Discovering Combinatorial Affordances of Elements to Form Gestalts: Learning to "See Ideas via Groupitizing and Visual Word Forms Colloque - Bruce McCandliss : Discovering Combinatorial Affordances of Elements to Form Gestalts: Learning to "See Ideas via Groupitizing and Visual Word Forms Bruce McCandliss Résumé Early education is a time of transformation in the way children come to see ideas in the world in the world, partly by a process of learning to combine visual elements to form gestalts. In this talk, I will expand upon these combinatorial learning phenomena across two systems that are transformed in the mind and brain by education. First, I will review research on groupitizing, the ability of children to combine their knowledge of small subitizable sets to access the cardinal value of larger sets, and how this emerging ability is intrinsically linked to educational achievement and potentially linked to individual differences in the organization of cortical activity. Secondly, I will review research on the cognitive and neural basis of learning to see visual word forms via combinations of letters, a process also intrinsically linked to success in education. | |||
| Colloque - Pedro Pinheiro-Chagas : Spatiotemporal Dynamics of Arithmetic Computation in the Human Brain | 02 Oct 2025 | 00:19:25 | |
Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Theme: Numerical and Mathematical Development Spatiotemporal Dynamics of Arithmetic Computation in the Human Brain Colloque - Pedro Pinheiro-Chagas : Spatiotemporal Dynamics of Arithmetic Computation in the Human Brain Pedro Pinheiro-Chagas Résumé Mathematics is among humanity's most remarkable achievements, yet we still lack a comprehensive understanding of how the brain performs even simple arithmetic. In this talk, I will present a series of studies investigating the encoding of elementary math, as well as the architecture, spatiotemporal dynamics, and causal role of the underlying brain networks. I will show that arithmetic computations selectively activate a distinct network in the human brain, which dissociates from language areas and overlaps with regions related to object recognition, visuospatial attention, working memory and relational reasoning. Next, using machine learning and intracranial recordings in humans, I will demonstrate how we can precisely track the cascade of unfolding representational codes during mental arithmetic, shedding light on the roles of each hub of the math network. Overall, this talk will provide insights into how elementary math concepts are implemented in the brain and, more broadly, show how the case study of math cognition can help us understand the algorithms of human intelligence. | |||
| Colloque - Evelyn Eger : Pattern Codes for Numerical Quantity during Perception and Internal Computation in the Human Brain | 02 Oct 2025 | 00:14:45 | |
Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Theme: Numerical and Mathematical Development Pattern Codes for Numerical Quantity during Perception and Internal Computation in the Human Brain Colloque - Evelyn Eger : Pattern Codes for Numerical Quantity during Perception and Internal Computation in the Human Brain Evelyn Eger Résumé During the last two decades, neuroimaging has generated a wealth of knowledge on how number processing inserts itself into the functional neuroanatomy of the human brain. We understand quite well now what are the cortical areas involved, and the neural codes for individual quantities as perceptual entities. Still, we lack a general understanding of how quantity representations are transformed during mental computations, and how or even where results of such computations are coded in the brain. By using ultra-high-field (UHF) imaging during an approximate calculation task designed to disentangle in- and outputs of a computation from the operation, we uncovered a representation of internally generated quantities which was most prominent in higher-level regions like the angular gyrus and lateral prefrontal cortex, and the intra-parietal sulcus. Intraparietal sensory-motor integration regions were the only ones found to share the same representational space for stimulus-evoked and internally generated quantities. This suggests the transformation may occur in these regions, before result numbers are maintained for task purposes in higher-level areas in a format possibly detached from sensory-evoked inputs. Results illustrate the power of UHF imaging to finely characterize neural codes underlying human numerical abilities with non-invasive methods. | |||

I will review the field's evidence, highlighting data from across 4 Continents. | |||
| Colloque - Edward Hubbard : Illuminating Fractions Learning: Neuronal Recycling of Non-Symbolic Ratios for Symbolic Fractions | 02 Oct 2025 | 00:39:07 | |
Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Theme: Numerical and Mathematical Development Illuminating Fractions Learning: Neuronal Recycling of Non-Symbolic Ratios for Symbolic Fractions Colloque - Edward Hubbard : Illuminating Fractions Learning: Neuronal Recycling of Non-Symbolic Ratios for Symbolic Fractions Edward Hubbard Résumé Within mathematics, fractions hold a special place. They present perennial difficulties to students, and yet, mastering fractions is a critical stepping stone towards algebra and higher-order mathematics. More than 20 years ago, Stanislas Dehaene suggested that fractions are difficult because they lack the intuitive perceptual foundation that permits us to readily comprehend whole numbers and instead may depend on formal and symbolic processes. Here, I will present research from my lab showing that fractions may indeed have a perceptual foundation, and that this perceptual foundation may be recycled to allow us to understand symbolic fractions. Behaviorally, we have shown that symbolic fractions do not need to be processed componentially and instead can be represented on a coherent mental number. We show that wholistic fraction comparisons (and translation to decimals) does not require time consuming computations, and that non-symbolic ratio perception in college students and American elementary school children predicts formal fractions skills. Using fMRI, we have further shown that non-symbolic ratio perception reliable recruits right parietal cortex, even before the onset of formal schooling, and these parietal systems become tuned to symbolic fractions after as little as two years of formal education. Despite this evidence that fractions do, indeed, have a perceptual foundation, they still present significant difficulties. I will close by arguing that fractions (and other domains) may be difficult not due to a lack of foundational systems, but rather, due to educational methods that fail to align with these perceptual foundations. Furthermore, I will argue that research in numerical cognition can (and should!) provide new pedagogical approaches that better align with the foundational systems we have discovered to help students better grasp higher-order mathematical concepts. | |||

I will show that this notion and the further theoretical observations and generalizations regarding movement are useful in accounting for language impairments. I will describe syntactic impairments of various sources: acquired (following stroke, tumour, tumor resection), developmental, and neurodegenerative (progressive aphasia, Parkinson's Disease, Machado Joseph Ataxia), and show how useful a good syntactic theory is in assessing, describing, and treating these impairments. | |||

I will illustrate this bidirectional approach by focusing on Disorders of Consciousness (i.e.: vegetative states also coined unresponsive wakefulness syndrome, minimally conscious state and related conditions), but I will also address more briefly key recent findings in epilepsy, hemispherotomy and sleep. | |||

Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Part 2: Training and Educating the Brain In Search of the Neural Code of Language Colloque - Jean-Rémi King : In Search of the Neural Code of Language Jean-Rémi King Résumé How does the brain transform words into meaning? By aligning insights from linguistics, neuroscience, and Large Language Models (LLMs), we observe that AI models and the human brain surprisingly converge on similar representational principles. Using neuroimaging and electrophysiology, we find that as LLMs improve at language tasks, their internal activations increasingly mirror cortical activity, and effectively enable us to decode meaning directly from these brain signals. Building on these results, we will outline a roadmap to uncover the neural code of language: (1) a benchmark dataset of brain recordings to build a "Rosetta Stone" across humans and models, (2) unique intracranial data from young children to characterize the computational principles of language development, and (3) a mathematical framework to understand the geometry of the neural representations of symbolic structures. Together, this research program moves us closer to deciphering how the human brain learns, represents and manipulates the structures of language. | |||

Stanislas Dehaene Chaire Psychologie cognitive expérimentale Année 2025-2026 Collège de France Colloque : Seeing the Mind, Educating the Brain Part 2: Training and Educating the Brain The Neuronal Basis of Numerical Cognition in Humans and Nonhuman Primates Colloque - Andreas Nieder : The Neuronal Basis of Numerical Cognition in Humans and Nonhuman Primates Andreas Nieder Institut de neurobiologie, département de biologie, université de Tübingen, Allemagne Résumé Our understanding of numbers, vital to our scientifically and technically advanced culture, has deep biological roots. Research across developmental psychology, anthropology, and animal cognition suggests that our ability to count symbolically arises from more primitive non-symbolic number representations. By studying single-neuron activity in associative brain areas of awake human patients and monkeys, we aim to uncover the physiological principles behind how numbers are represented in the brain. In both species, we've identified "number neurons" that encode set sizes regardless of how the stimuli are presented. These neurons play a crucial role in processing numerical information during goal-directed behavior. Moreover, investigating how numbers are processed in working memory offers insights into high-level cognitive control functions. Comparative research in numerical cognition is uniquely positioned to unravel the brain processes enabling humans to transition from nonsymbolic to symbolic representations, a hallmark of our species. | |||

| Colloque - Pieter Roelfsema: Conscious Perception: The Propagation of Selection Signals through the Global Neuronal Workspace | 01 Oct 2025 | 00:34:43 | |
Stanislas Dehaene Psychologie cognitive expérimentale Collège de France Année 2025-2026 Colloque: Seeing the Mind, Educating the Brain Part 1: Seeing and Decoding the Mind Conscious Perception: The Propagation of Selection Signals through the Global Neuronal Workspace Colloque - Pieter Roelfsema: Conscious Perception: The Propagation of Selection Signals through the Global Neuronal Workspace Pieter Roelfsema Netherlands Institute for Neuroscience, Amsterdam & Institut de la Vision, Paris Résumé he Global Neuronal Workspace (GNW) theory (Baars, 1988; Dehaene et al., 1998) proposes that information must be broadcast across widely distributed networks to enter conscious awareness. But what exactly is the information that is exchanged? I will argue that the GNW provides the substrate for the spread of selection signals and use this perspective to refine the distinction between access and phenomenal consciousness. Access consciousness corresponds to the information currently circulating within the GNW. In perception, this is the information selected by object-based attention, enabling a degree of representational flexibility that would otherwise not be attainable. In thought, access consciousness corresponds to the attended content of working memory, i.e. the items that can be actively transformed, combined, or used to retrieve associations. Phenomenal consciousness, by contrast, refers to the set of representations that are not yet part of the GNW, but that could be attended next because they are captured by the senses or because they are in an unattended memory form. I will illustrate these ideas in perception and memory. Perceptual experiments address the construction of coherent object representations through the spread of object-based attention, which at a neuronal level, corresponds to the spread of enhanced activity. In these studies, access consciousness aligns with object-based attention, and the GNW acts as the scaffold that allows selection signals to label all features of a perceptual object. This binding mechanism is incremental, time-consuming and explains why we consciously perceive unified, multi-feature objects. When considering memory, I will contrast iconic memory, supported by transient activity in early visual cortex, to working memory representations in higher areas that are maintained by persistent firing. Items in access awareness are attended within working memory and show stronger and more stable activity than non-attended items. I will show how the spread of selection signals among attended working memory items through the GNW supports conscious cognitive functions, such as resolving pronouns during reading and the retrieval of associations between concepts. Together, these findings suggest a revised view of the relationship between attention and consciousness, positioning the GNW as the orchestrator of distributed neuronal representations through the spread of attentional selection signals. | |||
| Colloque - Nancy Kanwisher: Intuitive Physical Reasoning in the Human Brain | 01 Oct 2025 | 00:32:47 | |
Stanislas Dehaene Psychologie cognitive expérimentale Collège de France Année 2025-2026 Colloque: Seeing the Mind, Educating the Brain Part 1: Seeing and Decoding the Mind Intuitive Physical Reasoning in the Human Brain Colloque - Nancy Kanwisher: Intuitive Physical Reasoning in the Human Brain Nancy Kanwisher MIT Résumé Visual scene understand requires much more than a list of the objects present in the scene and their locations. To understanding a scene, plan action on it, and predict what will happen next we must extract the relationships between objects (e.g., support and attachment), their physical properties (e.g., mass and material), and the forces acting upon them. One view is that we do this with the use of a "mental physics engine" that represents this information and runs forward simulations to predict what will happen next. Over the last several years we have been testing this idea with Josh Tenenbaum using fMRI. I will review evidence that certain brain regions in the parietal and frontal lobes (but not the ventral visual pathway) behave as expected if they implement a mental physics engine: they respond more strongly when deciding about physical than visual properties and when viewing physical versus social stimuli (Fischer et al, 2016), and they contain scenario-invariant information about object mass inferred from motion trajectories (Schwettmann et al, 2019), the stability of a configuration of objects (Pramod et al, 2022), and whether two objects are in contact with each other (Pramod et al 2025). Most tellingly, we can decode predicted collision events from perceived collision events, as expected if these brain regions run forward simulations of what will happen next. I will discuss the scope of engagement of this system by not just rigid "Things" but fluid "Stuff" (Paulun et al 2025), and (at least under some circumstances) by language. I will argue that these findings (as well as the poor performance of deep net models on many intuitive physical tasks) provide preliminary evidence for a physics engine in the human parietal and frontal cortex. | |||
| Colloque - Seeing the Mind, Educating the Brain : Introduction | 01 Oct 2025 | 00:23:57 | |
Stanislas Dehaene Psychologie cognitive expérimentale Collège de France Année 2025-2026 Colloque: Seeing the Mind, Educating the Brain Stanislas Dehaene: Introduction Colloque en anglais. Présentation Over the past decades, behavioral measures, brain imaging and neurophysiological recordings, in both humans and non-human primates, have led to major progress in understanding the neuronal and circuit-level properties that support cognitive functions such as visual recognition, spatial navigation and decision making. Human cognition is special, however, in its unique capacity to acquire new concepts and abilities through learning and education, particularly in the domain of language and mathematics. How far are we from understanding the neural mechanisms that allow us to acquire abstract concepts and symbols? Can we understand which cognitive toolkit is present in all brains since infancy, and how it changes with education? Can we separate the mechanisms of conscious and unconscious processing, and their respective contributions to human learning? To what extent does current animal research shed sufficient light on human computations? Are we still missing fundamental ideas, concepts, theories, and empirical tools to bridge between neuroscience and higher-level cognition? On the occasion of Stanislas' sixtieth birthday, he is delighted to invite some of the leading scientists—Jean-Pierre Changeux, Nancy Kanwisher, Elizabeth Spelke, Naama Friedmann, among others—who have played a key role in shaping his ideas. The program will feature discussions on the future of our field over the next two decades, along with a celebration of science, life, and friendship. | |||

Stanislas Dehaene Collège de France Psychologie cognitive expérimentale Année 2024-2025 Séminaire - Sommeil, replay et apprentissage - Tim Behrens : Structuring Knowledge in the Brain During Rest Intervenant(s) : Tim Behrens Computational Neuroscience Group at WIN Résumé When a waiter asks you for money at the end of a meal, how does your brain understand that it is the food you are paying for? Similar relationships are everywhere in the world and understanding them lets our brains choose good behaviours. Our brains contain a model of the relationships between objects and events in the world. What does this model look like? How is it built? When we come across a new problem, how can we fit it into to our current model? I will talk about current research in this area with a focus on exciting recent findings about what is going on during rest and sleep. When you are sleeping, or even sitting down for a cup of tea, your brain is not resting. It is busy updating and reorganising your model of the world. Finding shortcuts through your knowledge, making new inferences from your experiences. I will show some of the most interesting data in this emerging field of understanding. | |||

Nous avons tiré parti d'états hybrides entre l'éveil et le sommeil, notamment la somniloquie, le trouble comportemental en sommeil paradoxal, le rêve lucide et l'hypnagogie, pour observer directement le contenu mental pendant le sommeil, comme une fenêtre sur le processus en cours et sur la manière dont il contribue aux fonctions cognitives du sommeil, notamment la consolidation mnésique, la régulation émotionnelle, la simulation de menaces et la créativité. | |||

Le sommeil et la consolidation des apprentissages, de l'enfant à la personne âgée Intervenant(s) : Stéphanie Mazza Centre de recherche en neurosciences de Lyon Résumé Un bon sommeil est essentiel pour permettre un apprentissage efficient. Il permet d'être disponible au moment de l'encodage, mais il est aussi crucial après l'apprentissage pour permettre aux traces en mémoire de se consolider. Cette consolidation mnésique dépendante du sommeil est sous la dépendance d'activités cérébrales spécifiques qui évoluent tout au long de la vie. Nous analyserons au cours de cette conférence ces processus et leur évolution. | |||
