Functional Output of the Basal Forebrain
The basal forebrain is composed of many important components, one of which is the ventral striatum including the nucleus accumbens and olfactory tubercle. Both neuroanatomical and behavioral studies have provided important evidence implicating the ventral striatum as an interface between the limbic system and the extrapyramidal motor system (Kelley and Stinus, 1984; Heimer and Wilson, 1975; Mogenson and Nielson, 1984a). The ventral striatum receives allocortical projections from the hippocampus and amygdala (Kelley and Domesick, 1982), and a major dopaminergic projection from the ventral midbrain, especially the region of the ventral tegmental area. The availability of reliable behavioral measures and powerful neuropharmacological probes has allowed substantial progress to be made in the understanding of the functional significance of the ventral striatum and its circuitry.
