The thalamic region responsible for relaying gustatory (taste) information is the ventral posterior parvocellular part (VPPC).1

Located adjacent to the ventral posterior medial (VPM) nucleus, the VPPC receives secondary taste fibers and autonomic afferents. It subsequently projects this sensory information to the insula, the amygdala, and the region of the sensory cortex that lies near the areas representing the tongue.1
