After acquisition of a conditioned taste aversion (CTA) against sucrose, intraoral infusions of sucrose induce c-Fos-like immunoreactivity (c-FLI) in the medial intermediate nucleus of the solitary tract (iNTS) of the rat. In order to determine if c-FLI expression in the iNTS depends on subdiaphragmatic vagal afferent input to the NTS secondary to gastrointestinal symptoms during CTA expression (e.g. diarrhea), we quantified the induction of c-FLI in the iNTS by sucrose infusions after total subdiaphragmatic vagotomy in rats with a previously acquired CTA against sucrose. Rats were conditioned against infusions of sucrose by pairing sucrose infusions with toxic LiCl injections. After CTA acquisition, rats underwent bilateral subdiaphragmatic vagotomy or were sham-vagotomized. One week after surgery, rats received an intraoral infusion of sucrose. One hour after the test infusion, rats were perfused and processed for c-FLI. Vagotomy had no apparent effect on the behavioral expression of the previously acquired CTA, because both vagotomized and sham-vagotomized rats rejected all of the test intraoral infusion of sucrose. There was also no significant difference between vagotomized and sham-vagotomized rats in the number of c-FLI-positive cells in the iNTS after CTA expression. We conclude that c-FLI induction correlated with CTA expression is not dependent on subdiaphragmatic vagal efferent output or afferent input.
