Chemosensory Neurons
Chemosensory neurons are defined are those that discriminate between tastant as well as between the presence or absence of a tastant. In these neurons, the responses to reinforced (stimulated by tastant) licks in rats were greater than to those for the unreinforced (not stimulated by tastant) licks. They found that 34.2% of the GC neurons exhibited chemosensory responses. The remaining neurons discriminate between reinforced and unreinforced licks, or process task related information.
