Location: The shell is the outer region of the nucleus accumbens, and – unlike the core – is considered to be part of the extended amygdala, located at its rostral pole. Cell types: Neurons in the nucleus accumbens are mostly medium spiny neurons (MSNs) containing mainly D1-type (i.e., DRD1 and DRD5 ) or D2-type (i.e., DRD2 , DRD3 , and ...

NEUROSCIENCE MADE SIMPLER. Subscribe. Know your brain: Nucleus Accumbens. Where is the nucleus accumbens? Nucleus accumbens represented by a red dot. The nucleus accumbens is found in an area of the brain called the basal forebrain. There is a nucleus accumbens in each cerebral hemisphere; it is situated between the caudate and putamen.
The nucleus accumbens (nucleus accumbens septi) is located in the rostral and ventral forebrain, where the head of the caudate nucleus and the putamen are continuous (see Fig. 26.4).
