Brain chemistry calculations dictate how humans learn and make decisions

The brief

Neuroscientists are rewriting how we understand the brain chemical messengers that dictate our daily lives. Dr. Read Montague joins host Andrew Huberman to explain how dopamine and serotonin actively shape human decision-making, motivation, and learning.

Rather than acting as simple reward signals, dopamine and serotonin function as sophisticated computational systems. They constantly calculate the difference between what we expect to happen and what actually occurs, directly guiding our future choices.

At Virginia Tech, Montague researches these physical brain mechanisms to uncover how we assign value to actions. This computational approach helps explain why certain motivational states fail and how clinical interventions like SSRIs alter brain chemistry.
