Another brain area important for emotions is the nucleus accumbens, located above the amygdala.
If you like eating chocolate, doing so probably increases activation in this region of your brain, which
has been extensively studied because of its role in addiction to drugs such as alcohol and cocaine.
Both of these drugs increase firing of neurons in the nucleus accumbens and related areas. Feelings of
pleasure and anticipation of desirable outcomes are associated with a circuit of neurons that employ
the neurotransmitter dopamine, running from the ventral tegmental area through the nucleus accumbens
to the prefrontal cortex. Such brain circuits are reciprocal, with many feedback loops. Hence for
people like me, who love chocolate, the pattern of neural firing associated with eating it includes
neurons in the nucleus accumbens as well as parts of the brain involved in verbal, visual, and other
sensory representations.
