More specifically, GLP-1R expression has been identified in several hypothalamic and basal forebrain regions, including the paraventricular nucleus, supraoptic nucleus, infundibular nucleus/arcuate nucleus, lateral hypothalamic area, and nuclei of the basal forebrain, where they exhibit relatively well-defined regional expression patterns ( 3.4 Brainstem integration of gustatory and interoceptive signals 3.4.1 Anatomy of gustatory afferent pathways and signal convergence Following transduction by taste receptor cells, peripheral gustatory information is conveyed to the brainstem via afferent fibres associated with the facial nerve (VII, chorda tympani), glossopharyngeal nerve (IX), and vagus nerve (X) ( 3.4.2 NTS as an integrative node for taste and interoceptive state In addition to integrating gustatory information, the NTS receives chemical signals from the oropharynx and gastrointestinal tract, thereby serving as a hub for the early coupling of oral cues, visceral feedback, and feeding output ( 3.4.3 Brainstem GLP-1R expression and functional boundaries At the brainstem level, GLP-1 receptors (GLP-1Rs) are expressed in multiple neuronal populations within the NTS, including PPG neurons and GABAergic neurons ( In addition, endogenous GLP-1 neurons in the NTS project to the ventral tegmental area (VTA) and nucleus accumbens (NAc), pathways involved in food reward processing and the regulation of eating motivation and hedonic experience ( Together, these findings indicate that the NTS is not merely a passive relay of visceral information, but can actively influence both homeostatic and hedonic components of feeding
