Each half of the brain has one nucleus accumbens. It is located where the head of the caudate and the anterior portion of the putamen meet just lateral to the septum pellucidum. The nucleus accumbens and the olfactory tubercle collectively form the ventral striatum,
which is part of the basal ganglia.
The nucleus accumbens can be divided into two structures -- the nucleus accumbens core and nucleus accumbens shell. These structures have different morphology and function.
It is a collection of neurons within the forebrain.
It is thought to play an important role in
reward, laughter, pleasure, addiction, fear, and the placebo effect.
