Join us as we explore and map some new potential horizons for neuromodulation.

In this episode, we have an insightful conversation with Dr. Ali Rezai, who is the Associate Dean of Neuroscience at West Virginia University (WVU) and Executive Chair and Director of its Rockefeller Neuroscience Institute (RNI). We take a deeper dive into Dr. Rezai’s career, which features his notable achievement of performing 900 neurostimulator implants by 2006.

We highlight Dr. Rezai’s involvement in deep brain stimulation (DBS) and focused ultrasound (FUS), particularly in treating severe traumatic brain injury and addiction. This episode features interesting findings on the sustained effects of low-intensity FUS in addiction, as well as the possibilities of opening the blood-brain barrier for the treatment of Alzheimer’s disease.

Dr. Rezai shares more about RNI’s core mission and his leadership experiences in various medical societies, namely CNS, NANS, and ASSFN. We also discuss anecdotes from his presentations to various politicians, including President George W. Bush.

We cover a lot of ground in this episode, and it truly offers a comprehensive look into Dr. Rezai’s remarkable contributions to neuroscience and the broader medical field.

Dora Hermes and Kai Miller are associate professors at Mayo Clinic, where they have become a powerhouse on neuroscience, due to their strong collaboration and work in neural signal processing and analysis. Dora has a mathematics background, while Kai studied physics, including a PhD in physics, before becoming a functional neurosurgeon. Last year, both of them last authored a paper each at Nature Neuroscience, each with remarkable and groundbreaking findings about pretty different topics. The first paper dove into the organization of the primary motor cortex using invasive electrophysiological recordings in humans. The second measured conduction delays along fiber tracts in the developing brain.
We hope you enjoy this conversation as much as we did!

In our ongoing exploration of the DBS ecosystem throughout the podcast, we've engaged with leading voices in academia, clinical practice, and the patient community, each offering invaluable perspectives on the transformative impact of DBS. Yet, the journey from laboratory to bedside is a collaborative endeavor that requires another critical player: the industry. The symbiosis between innovative scientific research and robust industry support is crucial for the successful transition of groundbreaking therapies from concept to clinical application.

Today's feature is with Dr. Binith Cheeran, M.D., Ph.D., who is the Head of Brain Therapies at Abbott. Before joining Abbott, he spent more than 10 years treating patients as a clinical neurologist in Oxford and more than 15 years in academic research, work for which he was honored by the International Parkinson and Movement Disorder Society.

Marwan Hariz and Joachim Krauss need no introduction. First, because they are famous, and second, because they have been on the show, before. In fact, Marwan Hariz is the first to have been on the podcast three times, first, as an early adopter and trustee in episode 3, second, together with Joachim Krauss and Christian Moll in episode 33, and now again with Joachim in the present episode. I met Joachim in Grenoble at a meeting celebrating the 30th year anniversary of STN-DBS. He mentioned that the last episode had been fun, and that it could be great to do an episode on the history of pallidotomies. Needless to say, I would always spend as much time as I can get to speaking with these legends in the field, so of course we went ahead with the idea. I think there are few people that know as much about the history of stereotactic surgery as Joachim and Marwan. In fact, recently, they have been designated as the Historians of the ESSFN and also of the WSSFN (the latter together with Rees Cosgrove).

In this conversation, I learned that pallidotomies came in two waves throughout history, and we may be witnessing the beginning of the third wave now with the growing popularity of focused ultrasound surgery. So sit back and enjoy while Marwan and Joachim take us on a ride through the centuries to shed light on the convoluted historical path of the surgical procedure we call pallidotomy.

So far, in the podcast, I have been interviewing key opinion leaders from academia and clinical practice, and sometimes individual patients that graciously shared their insights after undergoing DBS. However, beyond patients and clinicians, there is a third component necessary for DBS to be successful, which are our partners in the industry. Without great industry leadership, it is hard if impossible to translate scientific findings into clinical practice. For instance, when the Grenoble team developed deep brain stimulation back in the 80ies and 90ies, they needed a strong industry partner to bring their breakthrough therapy into clinical practice. In some of the upcoming episodes including the present one, I will interview executives from the device industry.

Who better to start this journey with than Todd Langevin, who has been a key figure in the field of DBS and neuromodulation on the industry side. Following the success of Benabid’s team in Grenoble, inside Medtronic, Todd led the internal venturing team that pitched, developed and launched DBS, which is now an $800M business worldwide. So – in a sense – we may owe it to Todd’s team similarly as much as to the scientific and clinical team of investigators in Grenoble that DBS has become a therapy that is being applied, world-wide. During his 20 years at Medtronic, Todd grew the DBS business to a $350 million unit revenue. After a brief hiatus in the cardiac world, he moved back into the field of DBS to lead the startup Functional Neuromodulation as CEO, which aims at establishing DBS to the fornix as a treatment for Alzheimer’s Disease. Indeed, under Todd’s leadership, the company achieved a CE mark for the treatment in Europe. Finally, in 2021, Todd moved to Biotronik, where he currently is the President of the Neuromodulation Business.

In this special episode of Stimulating Brains, we dive deep into the intricacies of the human brain with two esteemed guests, Mac Shine from Sydney University and Paul Cisek from the University of Montreal. Building upon our earlier conversation with Mac in episode 9, this episode sees these brilliant minds sharing their insights on the basal ganglia, the role of dopamine, and the fascinating interplay between various brain regions. In addition, we explore the modulation of the thalamus by the basal ganglia, discussing its impact on both the cortex and the brainstem. Moreover, the conversation takes us on a journey through the evolution of the brain, examining the concept of the phylogenetic refinement approach. Join us in this intellectually stimulating episode as we explore groundbreaking concepts that could significantly impact both systems and clinical neuroscience. 

In this conversation with Jennifer ('Niffy') Thomas and Dr. Michael Stanley, we talk about how Niffy became an artist after undergoing DBS surgery to treat her early onset Parkinson's Disease. Dr. Michael Stanley is a cognitive neurologist at the Brigham & Women's Hospital and has special interest in art and the brain: He studies how lesions or other neurological conditions can lead to cessation of artistic behavior or how they can change the artistic style of artists. When he read about Niffy's case, he reached out to her and the two had multiple conversations about it. In preparation to this conversation, we were in contact with Dr. Paul Krack (Bern) who has studied and published upon similar cases in which DBS surgery changed or initiated artistic behavior. There is so much we can learn from Niffy and I am very grateful for her taking the time to share her story: Indeed, in her youth, Niffy did not enjoy art class at school and never had a particular interest in painting. She expressed herself differently: Via athletic competition or by playing the piano. But after coming home from DBS surgery in 2019, all of a sudden, there was this imminent urge – to paint...

In this conversation with Dr. Vanessa Milanese, we cover the importance of anatomy in neurosurgery and explore her intriguing work in both fields – and how they cross-informed one another. Vanessa is a functional neurosurgeon at A Beneficencia Portuguesa Hospital in São Paulo, Brazil and holds an adjunct assistant professorship of neurosurgery at Mayo Clinic in Jacksonville, Florida. We talk about her stellar work in combining her neurosurgical activity with anatomical work – which involves dissections of the white matter of postmortem brains using the Klingler’s method. We will talk about the rare community of neurosurgeons involved in similar activities, world-wide and the big influence Dr. Al Rhoton had on the field and on Vanessa’s career. We thoroughly enjoyed this conversation and learned a lot – and we hope you will enjoy it as much as we did! Thank you so much for tuning in!

In this episode, we sit down with Dr. Kullervo Hynynen, a key figure in biomedical ultrasound and image-guided therapeutics. Starting from his academic roots at the University of Aberdeen to his current roles at the Sunnybrook Research Institute and the University of Toronto, Dr. Hynynen has played an instrumental role in advancing medical imaging.

He has been at the forefront of investigating the use of focused ultrasound for various medical procedures such as non-invasive surgery, vascular surgery, targeted drug delivery, and gene therapy. Without his groundbreaking contributions, the medical field might not possess the capability to execute MR-guided focused ultrasound surgeries today.

For those curious about the specifics of his contributions, the Focused Ultrasound Society has a comprehensive website detailing milestones in the therapy's development, where Dr. Hynynen's name frequently appears.

Dr. Hynynen leads an extensive group at Sunnybrook, comprising approximately 50 to 100 members. These professionals span across the vast spectrum of focused ultrasound applications in both animals and humans.
