The ventral posterior parvocellular part (VPPC) of the thalamus serves as a relay station for gustatory (taste) sensation. This region receives secondary taste fibers as well as autonomic afferents originating from the cardiovascular and gastrointestinal systems.1

To process these signals, the VPPC projects directly to the insula—specifically to the sensory cortex region adjacent to the area representing the tongue—and to the amygdala.1
