In this fascinating episode of Research Renaissance, host Deborah Westphal sits down with Dr. Heather Brenhouse, professor of psychology and director of the Developmental Neuropsychobiology Lab at Northeastern University—and a 2024 Toffler Scholar. Together, they explore the deep connections between childhood adversity, brain development, and long-term mental health.

Dr. Brenhouse discusses why early life stress impacts some individuals more than others, how adversity can alter the timing of puberty, and why understanding neurodevelopment is essential to preventing psychiatric disorders. They also delve into the biology of behavior, the role of immune cells in the brain, and how evolving tools in neuroscience are helping uncover hidden patterns that shape health outcomes later in life.

🔬 Topics include:

• What a neuropsychobiology lab really studies
• How early stress accelerates brain and body development
• The surprising link between early adversity and puberty
• Why male and female brains respond differently to early life challenges
• How microglia and inflammation relate to long-term brain health
• The future of neuroscience research—from metabolic studies to computational modeling
• How eastern and western medicine might converge around mind-body health
  
  
  

Whether you're a researcher, student, or curious lifelong learner, this episode sheds light on how early experiences shape us—and what that means for preventing disease and promoting wellness across a lifetime.

In this fascinating episode of Research Renaissance, host Deborah Westphall welcomes Dr. Alysson Muotri, a professor in the Departments of Pediatrics and Cellular & Molecular Medicine at the University of California, San Diego., for a deep dive into what makes the human brain unique—and how understanding that uniqueness might unlock new treatments for neurological disorders. From stem cell brain models grown in the lab to sending "mini-brains" into space, Dr. Muotri shares his bold, unconventional path to advancing neuroscience and personalized medicine.

Dr. Muotri discusses his work creating 3D brain organoids to model human neurological development, including conditions like autism and epilepsy. He explains how modern humans evolved slower brain development than our ancestors, and how that developmental window leaves us vulnerable to mutation and disease—but also offers the complexity that makes human cognition and collaboration possible.

The conversation also touches on ethical frontiers, including the potential for lab-grown brains to develop consciousness, the future of neuroscience in space, and how traditional Amazonian medicine may offer clues to protecting the brain.

In This Episode:

• Why collaboration and sociality are key traits of the human brain
• How brain organoids help us study disorders like autism without invasive methods
• Using Neanderthal DNA to uncover what’s uniquely human
• Why space accelerates brain aging—and how that might fast-track drug discovery
• The ethical questions we must face as lab-grown brain tissues become more advanced
• How Dr. Muotri’s personal journey as a father shaped his scientific mission
• The need for alternative funding models to support bold, high-risk science

Quotes to Remember:
🧠 “We’re not just studying the brain. We’re building avatars of it.”
🚀 “Thirty days in space aged our brain organoids by ten years.”
🧬 “Autism may be the price we pay for having evolved a social brain.”
🌱 “Maybe the cure for Alzheimer’s is growing in the Amazon. We just have to look.”

In this episode of Research Renaissance, host Deborah Westphal welcomes Dr. Yvette Wong, Assistant Professor of Neurology at Northwestern University and 2024 Toffler Scholar, for a deep dive into the dynamic inner world of cells—and how her lab is uncovering new clues about neurodegenerative diseases by studying the microscopic interactions between organelles.

Dr. Wong discusses how organelles like mitochondria and lysosomes don’t just function in isolation—they actually “talk” to each other at contact points within cells. These cellular conversations may hold the key to unlocking better understanding and treatments for conditions like ALS, Parkinson’s, and Huntington’s disease.

Through vivid analogies (like buses exchanging cargo), Dr. Wong helps translate complex science into clear visuals, while also highlighting how advances in super-resolution live-cell microscopy and data analysis are transforming what’s possible in neuroscience.

🔬 Topics Covered:

• What organelles and organoids are—and why they matter
• The importance of mitochondrial-lysosomal contact sites in brain cells
• How defects in organelle crosstalk may contribute to diseases like ALS and Parkinson’s
• Why time-lapse microscopy is revolutionizing our understanding of disease mechanisms
• How Huntington’s disease mutations affect cellular cleanup systems
• The promise (and challenge) of modeling decades-long diseases in a lab
• Dr. Wong’s vision for the future of neuroscience—and the dream experiment she hopes technology will make possible
