• #73: Eyal Zadicario – Beyond the Scalpel: Towards an Acoustic Neurosurgical Suite with Insightec

  In this episode of Stimulating Brains, we sit down with Dr. Eyal Zadicario, Chief Operating Officer at Insightec, to explore the remarkable evolution of focused ultrasound – from its experimental origins to its transformative role in functional neurosurgery today.Dr. Zadicario shares insights from over two decades at the forefront of innovation, reflecting on the challenges of translating breakthroughs from academia to industry, designing clinician-friendly systems that prioritize the patient experience, and overcoming skepticism toward disruptive technologies.Together, we revisit key milestones – from the first MRgFUS based thalamotomy in 2008 and early applications in breast cancer, to the expanding frontiers of neuromodulation. Looking ahead, we discuss the exciting possibilities of blood brain barrier opening, the acoustic neurosurgical suite, and even brain mapping through focused sound.Tune in for a fascinating conversation on how precision acoustics are reshaping the landscape of brain therapy and beyond.

• #72: John Rolston — Closed-Loop Stimulation, Seizure Dynamics, and the New Frontiers of Epilepsy Treatment

  Today, we had the privilege of speaking with Dr. John Rolston, a leading voice at the intersection of neurosurgery, epilepsy, and brain stimulation.Dr. Rolston is an Associate Professor of Neurosurgery at Harvard Medical School and the Director of Epilepsy Surgery at Brigham and Women’s Hospital. His pioneering work bridges clinical neurosurgery and computational neuroscience, focusing on how electrical stimulation can modulate dysfunctional brain networks to treat epilepsy, movement disorders, and disorders of consciousness.In this episode, we explored the complexities of neuromodulation—what makes stimulation effective, why patient-specific targeting matters, and how brain states influence therapeutic outcomes. Dr. Rolston also shared his lab’s work on traveling waves in the brain and how these insights are transforming seizure localization and surgical decision-making. From closed-loop stimulation to stem cell therapy for Parkinson’s disease, Dr. Rolston walks us through the evolving landscape of functional neurosurgery and its future.

• #71: Harold Sackeim - The founding editor of Brain Stimulation and a founding figure in modern electroconvulsive therapy

  Today we had the privilege of speaking with a true pioneer in the field of neuropsychiatry and brain stimulation— Dr. Harold Sackeim.Dr. Sackeim is perhaps best known for his extensive research on electroconvulsive therapy (ECT), but his contributions span a wide range of topics from treatment-resistant depression to the placebo effect in neurostimulation. As a founding figure in modern ECT research, he has played a central role in shaping both the science and the clinical practice of brain stimulation therapies.In this episode, we explored the history and future of ECT, the controversies surrounding it, and Dr. Sackeim’s insights on the direction of neuromodulation. He explains how ECT has long been the most effective treatment for severe, treatment-resistant depression. While once overlooked in favor of medication, we now know that both the placement and intensity of stimulation are key—challenging the old belief that seizures alone drive its effects.

• #70: Rees Cosgrove – When Neurosurgery Chooses You: Rediscovering the Lost Art of Lesions and the Future of Brain Stimulation

  In this episode, we journey through the remarkable career of Dr. Rees Cosgrove—a trailblazer in functional neurosurgery, Director of Epilepsy and Functional Neurosurgery at Brigham and Women’s Hospital, and Professor of Neurosurgery at Harvard Medical School.Dr. Cosgrove reflects on his formative years training in the very halls that were roamed by legends such as Wilder Penfield at the Montreal Neurological Institute, and takes us through pivotal chapters of his career leading programs at Massachusetts General Hospital, Brown University, and now the Brigham. With a repertoire that spans from the golden era of ablative neurosurgery to modern deep brain stimulation and MR-guided focused ultrasound—where he has performed over 600 sonications—Dr. Cosgrove provides a unique perspective on how the field has transformed over the past several decades.Throughout the conversation, we delve into the history and resurgence of surgical lesions for psychiatric and neurological conditions, the nuances of neuromodulation technologies, and the evolution of imaging that now defines precision in brain surgery. Dr. Cosgrove also shares his views on mentorship, the transmission of surgical wisdom, and how we can preserve the disappearing art of lesioning in an age increasingly dominated by stimulation.Whether you're a neurosurgeon, neuroscientist, or simply curious about how we interface with the brain to treat disease, this episode is a rare and insightful look into the mind of one of the field’s most experienced and thoughtful pioneers.

• #69: Terence Sanger – Pushing Boundaries in Pediatric DBS: From Multi-Electrode Stimulation to Closed-Loop Strategies

  In this episode we will dive deep into the minds of leading researchers and clinicians in the field of neuromodulation. Today, we are thrilled to have Dr. Terry Sanger with us.Dr. Sanger is a renowned pediatric neurologist, engineer, and Chief Scientific Officer at CHOC, where he focuses on improving the lives of children with movement disorders—especially dystonia. He’s well known for combining deep computational approaches with cutting-edge neuromodulation techniques.In this episode, we’ll uncover how his background in engineering, neuroscience, and clinical practice converges to shape new possibilities for treating complex movement disorders in children. From pioneering multi-electrode deep brain stimulation for pediatric dystonia to his latest forays in closed-loop stimulation research, Dr. Sanger is truly expanding the boundaries of what’s possible in pediatric care.
