Abstract
- Fos-like immunoreactivity (FLI) can indicate the location of neurons activated following expression of conditioned taste aversion (CTA). After one conditioning trial FLI has been identified in the intermediate nucleus of the solitary tract (iNTS) with little expression in other brain regions. The present study assessed the effect of increasing aversion strength on the magnitude and anatomical distribution of FLI during CTA expression. When animals received three rather than one conditioning trial, significant FLI was seen not only in the iNTS but also in the parabrachial nucleus (PBN), and the central nucleus of the amygdala (CNA), regions thought to be important in taste aversion learning.
