Research Interests
Dr. McIntyre’s research centers on developing a fuller understanding of the mechanisms of neuroplasticity as reflected in both epilepsy and learning/memory. The experiments are broadly based in electrophysiology, anatomy and behaviour. The electrophysiological work is often accomplished in whole animals and makes extensive use of the kindling model of epilepsy. Additional electrophysiological studies are conducted using in vitro slice preparations of various temporal areas. Most particularly the work concentrates on the perirhinal cortex and its relationships both anatomically and functional with other limbic structures, most notably the piriform and entorhinal cortices, the amygdala and hippocampus. In this work, the perirhinal cortex is showing itself to be important in both convulsive seizure development and several forms of learning. Research is supported by the Natural Science and Engineering Research Council of Canada and the Canadian Institutes for Health Research (CIHR).
