Electrical stimulation of the waist area (W) of the parabrachial nucleus (PBN) in conscious rats elicits stereotypical oromotor behaviors . To identify neurons possibly involved in these behavioral responses, we used Fos immunohistochemistry to locate populations of neurons within central gustatory and oromotor centers activated by PBN stimulation. Dramatic increases in the numbers of Fos-like immunoreactive neurons were observed in the ipsilateral PBN, nucleus of the solitary tract (NST), and central amygdala. The increase in neurally-activated cells within the ventral subdivision (V) of the rostral NST is particularly noteworthy because of its projections to medullary oromotor centers. A modest increase in labeled neurons occurred bilaterally within the gustatory cortex. Although there were trends for an increase in Fos-labeled neurons in the gustatory thalamus and medullary reticular formation, most changes in labeled neurons in these areas were not statistically significant. Linear regression analysis revealed a relationship between the number of taste reactivity (TR) behaviors performed during PBN stimulation and the number of Fos-like immunoreactive neurons in the caudal PBN and V of the rostral NST. These data support a role for neurons in W of the PBN and the ventral rostral NST in the initiation of TR behaviors.
