Are You Really You, or Just a Pattern Your Brain Built with Dr. Masud Husain
Summary
Host Chris Stemp interviews neurologist Dr. Masood Husain about his book *Our Brains, Ourselves*, exploring how the brain constructs identity through memory, motivation, and social connection. Husain uses case studies of patients with brain injuries to demonstrate the fragility of the self, showing how damage to specific neural circuits can fundamentally alter personality and behavior. The discussion highlights that identity is not static but a dynamic process built on biological foundations, offering insights into how we define who we are.
