Your Brain is Tough
Resilience isn't just a personality trait—it's something the brain actively builds.
In this episode of Road to Resilience, host Stephen Calabria speaks with Eric J. Nestler, MD, PhD, one of the world's foremost neuroscientists, about the remarkable capacity of the brain to adapt in the face of adversity.
Drawing on decades of groundbreaking research into depression, addiction, and stress, Dr. Nestler explains why trauma doesn't affect everyone the same way, how resilience is shaped by both biology and experience, and what science is revealing about the brain's extraordinary ability to recover and change.
The episode explores why supportive relationships matter, how chronic stress alters the brain, whether resilience can be cultivated at any age, and the everyday habits that can help strengthen our minds throughout life.
Stephen Calabria: [00:00:00] From the Mount Sinai Health System in New York City, this is Road to Resilience, a podcast about facing adversity. I'm your host, Stephen Calabria, Mount Sinai's Director of podcasting. It turns out our brains are tougher than we'd thought.
Every challenge we face, joy we experience, relationship we build, they all leave a mark on our brain. On today's episode, we have Dr. Eric Nestler, a renowned neuroscientist and the dean of the Icahn School of Medicine at Mount Sinai.
Dr. Nestler spent his career exploring how stress, trauma, depression, and addiction reshape the brain and why some people recover while others remain stuck.
We'll explore what modern neuroscience can teach us about overcoming adversity, protecting our brain health, and cultivating resilience, not as an abstract ideal, but as something each of us can strengthen one experience at a time.
Dr. Eric Nestler, welcome to Road to Resilience.
Dr. Eric Nestler: Thanks for having me.
Stephen Calabria: So sir, you've spent decades studying why some [00:01:00] people develop depression or addiction after adversity, while others seem to emerge stronger. One might call it brain resilience.
When people hear the phrase a resilient brain, what do you hope they understand that they may not already know?
Dr. Eric Nestler: Sure. There's broad variation in the ability to adapt or cope with challenges that we face in everyday life. Two examples of that would be our vulnerability to become addicted after trying a drug of abuse, or the ability to remain functional, happy, healthy, despite being subjected to horrible stress.
