Where is the nucleus accumbens located in the brain?
Quick Answer
The nucleus accumbens is deep in the forebrain, in the basal forebrain/ventral striatum region. It plays a major role in reward, pleasure, motivation, and reinforcement learning.
The Full Story
The nucleus accumbens lies in the ventral part of the striatum, deep in the basal forebrain. It receives dopamine input from the ventral tegmental area and contributes to reward processing, motivation, and action selection. Psychologists and neuroscientists often study it because it is active when people anticipate rewards or learn from reinforcement. It is also implicated in addiction, where reward circuits can become dysregulated.
