| Research Abstract |
To investigate neuronal processing in perirhinal cortex during stimulus-stimulus-reward associations, we recorded single unit data from neurons in the perirhinal cortex using two monkeys performing bar-release response trials imbedded within a delayed conditioning paradigm. The neurons in the perirhinal cortex have signals about stimulus identity, predicted reward contingency, and memory for a preceding stimulus. The pattern cue elicited responses during the conditional association task were not simply related to physical stimulus characteristics. These results showed that most of the neurons had activity distinguishing the conditional association task, suggesting an important role of perirhinal cortex when stimulus-stimulus sequences lead to different reward outcomes.
