nucleus accumbens. A limbic nucleus that sits at the ventral head of the striatum, contiguous with the caudate and putamen and adjacent to the olfactory tubercle. The nucleus accumbens is part of the ventral striatum nuclei. Synapses in the nucleus accumbens use dopamine as their neurotransmitter.Increasing the activity of these synapses (i.e., increasing the level of dopamine in the nucleus) leads to a rewarding or pleasurable sensation.ynapses in the nucleus accumbens use dopamine as their neurotransmitter.
