Figure 1.
Schematic representation of neuroanatomical connections between the gastrointestinal (GI) tract and central nuclei involved in the regulation of gastrointestinal functions. Note that the location of nuclei is not intended to be anatomically accurate. AP—area postrema; DMV—dorsal motor nucleus of the vagus; NTS—nucleus of the tractus solitarius; PB Complex—parabrachial complex (i.e., parabrachial nucleus + Kölliker-Fuse nucleus); PAG—periaqueductal gray; CeA—central nucleus of the amygdala; Vestibular N—vestibular nucleus; Trigeminal N—trigeminal nucleus; Raphe N—raphe nuclei.
