Central Processing Time for a Conditioned Response in a Vertebrate Model System

  • David H. Cohen
Part of the Advances in Behavioral Biology book series (ABBI, volume 26)

Summary

For some years we have been developing visually conditioned heart rate change in the pigeon as a vertebrate model system for cellular analyses of associative learning. The behavioral model is now well-established, and substantial progress has been realized in delineating the neuronal circuitry mediating the conditioned response. With this information as a foundation we have been able to initiate cellular neurophysiological studies to (a) describe the temporal properties of the information flow along the identified pathways during conditioned responding, and (b) identify sites of training-induced modification. This report deals with the temporal properties of the information flow, and the results indicate that central latencies and processing time are surprisingly short. Thus, the system may be considerably more “analyzable” than might have been anticipated.
