Dopamine System, Craving & Pursuit Explained | Dr. Andrew Huberman

Dr. Andrew Huberman explains the relationship between dopamine peaks and baselines, emphasizing that a drop below baseline following a peak of desire is crucial for motivating action. Using the example of craving a sandwich, he illustrates how the anticipation of a reward causes a dopamine increase, which then dips below baseline, prompting the individual to pursue the desired item. The actual reward then brings dopamine back up, with the level depending on whether the outcome met or exceeded expectations, a concept known as reward prediction error. This system, he notes, applies to any desire and pursuit, not just food.
