Description

In this episode, I sit down with Dr. Josh Gross, a neuroscientist and pharmacologist at Penn State University, to break down the neurobiology of addiction, food, and cravings. We explore how dopamine, ghrelin, and receptor signaling shape the brain’s reward system, and how these same pathways link addiction, hunger, and obesity.
