Can a map help us understand neurological disease? In this episode of Barrow On The Brain, we explore the fascinating intersection of geography and neuroscience with Dr. Brittany Krzyzanowski—a geographer studying neurological disease at Barrow—and Dr. Brad Racette, chair of neurology at Barrow and a pioneer in environmental neurology. Discover how spatial epidemiology, maps of Parkinson’s prevalence, and clues from wind patterns, croplands, and air pollution are helping scientists investigate environmental risk factors like pesticides and heavy metals. From rural farming regions in the U.S. to manganese smelters in South Africa, this episode unpacks how neurological research can zoom in on communities, uncover hidden threats, and potentially change public health outcomes—one dot on the map at a time.

In this powerful first episode of Barrow On The Brain, Barrow Neurosurgery Resident Dr. Mark Pacult shares the story of a young woman with a severe traumatic brain injury—her uncertain prognosis, the quiet moments in the ICU, and the long road to recovery. Alongside her story, Dr. Pacult speaks with Dr. Ruchira Jha, Dr. Christina Kwasnica, and Dr. Glynnis Zieman about the science behind brain healing, the role of inflammation, and the critical importance of rehabilitation. Through expert insights and lived experience, this episode explores what really happens after brain injury—and why recovery is far more complex than it seems.
