Excitotoxic lesions of the parabrachial nuclei prevent conditioned taste aversions and sodium appetite in rats.

Abstract

Electrolytic lesions of the parabrachial nuclei (PBN) disrupt conditioned taste aversion (CTA) in the rat, but it is not known whether this effect is due to damaging axons of passage or to destruction of intrinsic neurons. We tested 10 rats with electrophysiologically guided, ibotenic acid lesions of the PBN (PBNx) to determine whether they could acquire a… (More)
