Mallory Hacker is an Assistant Professor for Neurology in the team of David Charles, who is Professor of Neurology, Vice-Chair for Business Development and Strategy, as well as the Medical Director for Telehealth at Vanderbilt University Medical Center in Nashville, Tennessee. In 2006, after a stay at Alim Louis Benabids team in Grenoble, France, David started to investigate the question of whether subthalamic DBS could lead to slowing of motor progression in patients with early stages of Parkinson’s Disease. In a one-of-a kind trial, he collected data on the first patients which were published in 2014.In subsequent follow up trials, many of which were first-authored by Mallory Hacker, Class II evidence that supports this hypothesis could be established. It was a great joy to host Mallory in my lab in Berlin in 2022 and we have looked at the effects of lead locations on patients enrolled in the pilot trial. This is what convinced me that there might be something: The few patients that did not progress at all in their motor symptoms after two years were all precisely stimulated at the optimal location within the STN, while the ones that did progress, were more off target. Indeed, these same optimally placed patients had lower stimulation amplitudes and received less medication – but still had a clearly better outcome. Since the original trial, David and Mallory have been hard at work in trying to secure funding for a phase III pivotal trial, and we discuss how difficult this process has been, but also, that there is hope on the horizon, regarding the next steps!

Jens Volkmann is a Professor and the chair of Neurology at University Hospital Würzburg in Germany and one of the key DBS experts in the field. I have intensely collaborated with Jens and his team and he has been a mentor for me since a long time. In fact, in this conversation, Jens reminded me of exactly when we first met, during a summer school in cortona, italy, where I was fortunate enough to listen to fantastic talks by exciting faculty including Jens about the future of Deep Brain Stimulation. Jens has been a pioneer of image guided DBS and has come up with fantastic concepts and models around the mechanism of action of DBS. He has also largely contributed to advancing the fields based on clinical studies and is very broadly informed about the past, present and future of the field in both human and animal work around the technology. I hope you enjoy this conversation as much as I did, and thank you for tuning into Stimulating Brains!

Phil Starr is a Professor of Neurological Surgery at University of California, San Francisco and a developer of implantable brain devices. At UCSF, he co-directs a multidisciplinary neurology/neurosurgery movement disorders clinic together with Dr. Jill Ostrem. I’ve been a long-time admirer of Phil’s work and in this conversation we blaze through quite a few of his numerous publications. One key breakthrough and invention of Phils work has been to include Ecog recordings – both intraoperatively but also chronically – to investigate brain signals in various states. We talk about the Open Mind Consortium, Mentorship and the cross-pollination between academia and industry. One key highlight of Phils work is a paper which was accepted for publication in Nature Medicine, at the time of recording this just yesterday. In it, the three co-first authors Carina Oehrn, Stephanie Cernera and Lauren Hammer demonstrate the chronic use of a newly identified cortical physiomarker, which is now referred to as the finely tuned gamma activity. I hope you enjoy this conversation as much as I did, and thank you for tuning into Stimulating Brains!

When I interviewed Marwan Hariz for episode #4, he wrote in an email: "When you finish the series and all interviews, please let me know because then I should interview you as the Grand Finale of this series…". Throughout the recordings, I heard similar remarks from other guests but also, increasingly, from listeners of the show. After Nico Dosenbach suggested the same in #39, Mike Fox called me and offered to interview me for a round episode of the podcast. With this episode, Stimulating Brains turns #50, and we are indeed flipping the mike so I finally get to experience what I put my guests through on the podcast. Who could have been a better host than Mike for this conversation – as a mentor of tremendous importance, he has been around for (and facilitated) most of the key turning points in my career. Mike and I talk about a lot of things that even covers my youth (thanks to a guest question by Mike Okun), my passion for music, key stages of my career and of course connectomic deep brain stimulation and a thing my lab has begun calling 'the dysfunctome'. We also reflect on the purpose of the podcast and I get to talk at length about how rewarding an experience it has been for me. We then speculate about its future and the future of the field of neuromodulation. Writing this, I want to take the opportunity to thank you all for the continuous support of Stimulating Brains – and of course for tuning into this episode, as well!

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 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.

In this intriguing dialogue with Dr. Christelle Baunez, a neurobiologist at Aix-Marseille University, we discuss a mysterious and small structure, the subthalamic nucleus. Christelle is known as the STN woman in France, due to her dedication to study this structure over the years. Christelle is a pioneer in the side effects related to STN stimulation in Parkinson Disease patients. Now, she is working towards understanding how STN stimulation can help people with addiction. We cover, with an historical perspective how STN became an interesting brain stimulation target, their advantages and disadvantages of its stimulation, side effects related, its connectivity and current and future applications. In addition, we discuss some of her recent fully unpublish experiments, like STN stimulation in cocaine addicted macaques and beyond. We also cover Christelle’s advocacy for animal research and its important role to push the boundaries of neuroscience. Finally, Christelle shares her passion for photography and how STN should be included in the reward circuit. This conversation was an incredible learning experience for me, and I believe it will be for you too. Thank you so much for tuning in – for this round episode number 41 of stimulating brains!

In this engaging conversation with Casey Halpern, a functional neurosurgeon at Penn Medicine. Casey is a pioneer in both deep brain stimulation and focused ultrasound and with his lab has recently had some fantastic breakthroughs, especially, but not exclusively in the field of loss-of-control eating in severe obesity. We cover a lot of ground from optogenetics at Stanford, basic science research about the nucleus accumbens and translation of findings into patients, serendipitous discoveries in humans, to stereo-EEG procedures in patients with epilepsy. We discuss what made his recent Nature paper about an appetite mediating circuit in the human hippocampus so special, how he took his findings from 2013 in rodent work – across several stages – into a human clinical trial for eating disorders. We also cover Casey’s ongoing trial in DBS for OCD, where he adopts an approach to probe the brain with multiple electrodes to then identify optimal target areas for each individual patient – in line with other current advances of psychiatric neurosurgery. We also talk about MR guided focused ultrasound and the potential future of this treatment option in a tight relationship with DBS. As always, I learned a lot in this conversation and I hope you find it as enjoyable as I did. Thank you so much for tuning in – for this round episode number 40 of stimulating brains!
