    The Hidden Story of the Brain's Ventricles and Neurodevelopmental Disorders

    What can the brain’s ventricles tell us about how the brain develops? In this episode of Speaking of the Brain, I explore research connecting ventricular development, neural stem cells, hydrocephalus, and neurodevelopmental disorders such as autism and schizophrenia. We’ll look at how changes in these fluid-filled structures may offer clues about developmental processes beginning much earlier in the brain and the potential to serve as an early detection tool for neurodevelopmental disorders.

    My Journey in Neuroscience (Part 2): Investigating the Kidney-Brain Axis Through Spatial Transcriptomics In the Lab of Dr. Harshman, M.D., M.S.

    In Part 2 of "My Journey in Neuroscience", I share how my interests in neurodevelopment and kidney physiology came together through research on the kidney-brain axis in Dr. Harshman's lab at the University of Iowa. I discuss using spatial transcriptomics to investigate how pediatric chronic kidney disease may affect different regions of the developing brain and reflect on what I have learned from these experiences about curiosity and growth in research.

    My Journey in Neuroscience (Part 1): Inside the PEND Laboratory with Dr. Stevens, M.D., Ph.D.

    In this episode of Speaking of the Brain, I share the story of how my journey into neuroscience research began at the University of Iowa's PEND Laboratory led by Dr. Hanna Stevens, M.D., Ph.D. From studying the placenta's role in neurodevelopment to discovering the value of curiosity, mentorship, and persistence, I reflect on the research experience that shaped my passion for becoming a physician-scientist and for neuroscience.

    Inside BrainIAC!: The New AI Model Decoding Brain MRIs

    Description: In this episode of Speaking of the Brain, we explore BrainIAC, a new AI tool that analyzes brain MRI scans to help predict brain age, dementia risk, stroke timing, brain tumor mutations, and cancer survival. Tune in to hear about how AI may uncover hidden patterns in medical images and what this could mean for earlier detection, more personalized care, and hope for many patients.

    Listening to the Brain: Pushing the Parkinson's Disease Frontier with Adaptive Deep Brain Stimulation

    How can a brain implant adjust itself in real time? In this episode, we explore adaptive deep brain stimulation (aDBS), a newly FDA-approved technology that can sense abnormal brain activity and automatically respond to changing symptoms in Parkinson's disease. Learn how decades of research led to this breakthrough and how it could transform the future of neurological treatment.

    Interview with Dr. Debebe Theodros, M.D., Ph.D., Neurosurgery Resident at Stanford University: Mentorship, Resilience, and Finding Your Path in Medicine

    In this special episode of Speaking of the Brain, I sit down with Dr. Debebe Theodros, a neurosurgery resident at Stanford University and one of my mentors through the Harris Neuroscience Internship. We discuss Dr. Theodros’s journey into medicine and neurosurgery, the challenges of training in one of the most demanding medical specialties, and the mentors who helped shape his path. Dr. Theodros also shares valuable insights about resilience, learning from failure, and what it means to support the next generation of scientists. As someone who has learned so much from his mentorship, this conversation was especially meaningful to me. I hope listeners can take away a glimpse into the possible pathways for a neuroscientist and are encouraged to stay curious and keep moving forward even when things don’t go as planned.

    The Neuroscience Making Movement Muscle Memory

    How does the brain turn practice into muscle memory? In this episode, we delve into how movement and memory are encoded in the brain, as explored through the work of Stanford neuroscientist Dr. Jun Ding. Learn how neural circuits refine with practice, why skills become automatic over time, and what this research reveals about aging, dementia, and Parkinson’s disease.

    New Year, Same Brain: Why New Year’s Resolutions Are So Hard to Stick to

    Why do New Year’s resolutions start out strong and then fizzle so fast? On this episode of Speaking of the Brain, we dive into what your brain is really doing when you try to change. From habit loops to motivation crashes to decision fatigue, we’ll explore why sticking to goals is harder than it seems and how to outsmart your own brain.
