How Addiction Hijacks the Brain

Lecture no. 3 from the course: The Addictive Brain

How Addiction Hijacks the Brain

Taught by Professor Thad Polk | 32 min | Categories: The Great Courses Plus Online Science Course

Here you’ll examine the ways addiction alters the brain by numbing the pleasure center, sensitizing the dopamine system, and inhibiting the prefrontal cortex. Combined, these altered brain functions lead to strong cravings and a reduced ability to control one’s actions. This foray into neuroscience will forever change the way you think about addiction.
