striatum
Forebrain reward center
The striatum is a structure deep in the brain that processes movement, reward, and decision-making.
It receives input from the cortex and plays a central role in habit formation and motivation.
Dysfunction in the striatum is associated with Parkinson's disease, Huntington's disease, and addiction.
The name comes from the striped appearance of the tissue.
