Abstract

This study was investigated to hippocampal θ rhythm and multiple unit response during classical conditioning of rabbit`s nictitating membrane response. Hippocampal θ rhythm usually was classified into type 1 and type 2. According to various electrophysiological researches, type 1 θ rhythm was highly correlated with voluntary behavior and type 2 θ rhythm with automatic behavior, but there were studies which assert that type 1 θ rhythm was correlated with sensory information processing. So, this study was an attempt to investigate those results as compared paired conditioning group with unpaired control group. Paired group was presented 500msec tone CS followed 100msec air puff US after 400msec interstimulus interval. But unpaired group was presented 500msec tone and 100msec air puff independently. There was no difference in distinction of θ rhythm between the two group. Again, there was no correlation between θ rhythm and conditioned response. But, there was high correlation between multiple unit response and conditioned response. The result indicated that type 1 θ rhythm was highly correlated with presentation of tone and air puff in both group, this result suggest that type 1 θ rhythm is correlated with subject`s information processing.
