What if depression and anxiety are not just disorders of the brain, but conditions shaped by the entire body?

In this episode of Research Renaissance, host Deborah Westphal speaks with Dr. Scott Russo, Director of the Brain Body Research Institute at Mount Sinai, about a major shift underway in mental health science. His work challenges the long-standing brain-only model of psychiatric illness and explores how inflammation, immune signaling, and organ systems interact with the brain to shape mood, resilience, and disease risk.

From gut health to traumatic injury, this conversation reveals why mental health research is moving toward an integrative “systems biology” approach that could redefine treatment in the next decade.

Key Takeaways

• Mental illnesses often coexist with medical conditions, suggesting they are whole-body disorders rather than isolated brain diseases.
• Chronic inflammation may be a shared biological driver across conditions ranging from depression to cardiovascular disease.
• Signals from peripheral organs can influence emotional states, meaning some emotions may originate in the body before being processed by the brain.
• Environmental exposures, infections, and life experiences may account for the majority of mental health risk, with genetics contributing a smaller portion.
• Emerging therapies may target immune pathways or body-brain signaling rather than neurotransmitters alone.
• Collaboration across disciplines is essential to advancing mental health research, yet institutional silos still limit innovation.

About the Guest

Dr. Scott Russo is Director of the Brain Body Research Institute at the Icahn School of Medicine at Mount Sinai. His work focuses on understanding how immune, metabolic, and neural systems interact to influence psychiatric disorders and resilience.

Modern medicine is not shaped by science alone. It is shaped by ethics, trust, and the difficult decisions made when technology moves faster than society can understand it.

In this episode of Research Renaissance, legendary bioethicist Dr. Art Caplan reflects on a career that helped build the field of bioethics from the ground up. From surviving polio as a child to shaping national policies on organ transplantation, informed consent, and end-of-life care, Caplan offers a deeply personal and historically grounded perspective on how ethical thinking became essential to modern healthcare.

The conversation explores the lingering distrust born from COVID-19, the ethical blind spots of artificial intelligence, the environmental cost of data infrastructure, and why communication between science and the public may be the most urgent challenge ahead.

This episode is both a history lesson and a call to action. Ethics is not abstract philosophy. It is practical problem-solving for real people, real patients, and real consequences.

Key Takeaways

• Bioethics emerged to solve real clinical dilemmas, not theoretical debates.
• Policies such as informed consent, brain-death standards, and organ allocation were shaped by early bioethics work.
• Public trust in medicine declined significantly after COVID-19 due to shifting scientific guidance and poor communication.
• AI introduces ethical risks beyond autonomy and bias, including environmental strain, privacy vulnerability, and unclear liability.
• The U.S. healthcare system’s structure, not just its technology, drives many ethical failures.
• Ethics must move from academic journals into communities through direct engagement and public dialogue.

Parkinson’s disease begins decades before symptoms appear — and by the time tremors start, brain changes have already been unfolding for years.
In this episode of Research Renaissance, host Deborah Westphal speaks with Dr.

Zachary Sorrentino, neurosurgeon, physician-scientist, and 2025 Toffler Scholar at the University of Florida. Dr. Sorrentino explains how misfolded proteins like alpha-synuclein spread through the brain, how deep brain stimulation helps restore movement, and why preventing dementia in Parkinson’s patients may be the next major frontier.

Drawing from both the operating room and the research lab, Dr. Sorrentino shares how his team analyzes proteins directly from surgical tools used in living patients — offering unprecedented insight into disease progression.
This is a powerful conversation about aging, brain vulnerability, precision therapies, and the human side of neurosurgery.
