Schematic representation of the neuroanatomical connections between the gastrointestinal (GI) tract and central nervous system nuclei involved in regulation of GI functions and feeding. Note the location of the nuclei are not intended to be anatomically accurate. AP—area postrema; NTS—nucleus of the tractus solitarius, DMV—dorsal motor nucleus of the vagus; DVC—dorsal vagal complex; PBN—parabrachial nucleus; VTA/SN—ventral tegmental area/Substantia Nigra; PVN—paraventricular nucleus of the hypothalamus; VMH—ventromedial hypothalamus; LH—lateral hypothalamus; ARC—arcuate nucleus; CeA—central nucleus of the amygdala; BNST—bed nucleus of the stria terminalis.
