Subsections
The ventral pallidum is described as the limbic area of the pallidal complex as
many reward circuits converge on this region. It encodes reward and motivation
information engendered by rewarding stimuli (
Smith et al., 2009). The VP is divided into medial
and lateral sections (
Sesack and Grace, 2010).
The VP is innervated by inhibitory GABA connections from the
NAcc (
Basar et al., 2010).
See Nacc core/shell for the exact projections.
VP efferents project to the SNr, EP, prefrontal cortex, thalamus, LHb
and the VTA (
Groenewegen et al., 1993;
Ikemoto, 2007).
The ventral pallidum projects to the mediodorsal thalamic nucleus
which in turn then projects to the infralimbic, prelimbic, agranular
insular and cingulate cortex (Ikemoto, 2007).
The m-VP is the main source of GABAergic innervation to the VTA
(Sesack and Grace, 2010).
