Olfactory involvement in learning processes.

The purpose of this study is to investigate the existing relations between olfaction and acquisition of the two-way conditioned avoidance response (CAR). For this investigation we have used white adult male Wistar rats. Taking into consideration that several structures of the limbic system participate in learning and memory processes and also that olfactory pathway is believed to have connections with the limbic system, we thought it would be interesting to investigate, if peripheral anosmia influences the performance of rats in the two-way avoidance response. It was shown that peripheral anosmia in rats impaired conditioned avoidance response.
