Vertebrate Central Pathways

Abstract

The gustatory system in mammals provides sensory input that is critical for ingestive behavior and avoidance of toxic compounds. The sense of taste interfaces extensively with neural substrates of reward and motivation. Taste receptor cells are innervated by three cranial nerves: VII, IX, or X. Fibers of these nerves synapse in the medulla in the rostral portion of the nucleus of the solitary tract. Second-order projections synapse in the parabrachial nucleus (PbN) of the pons. From the PbN, the gustatory projection follows two pathways: a thalamocortical pathway and a limbic forebrain pathway. Coding of taste stimuli is represented by the relative activity across gustatory neuron types.
