Overview: I use a variety of electrophysiological and pharmacological techniques to examine how short- and long-term alterations in the strength of synapses occur, and how these changes may contribute to learning and memory within cortical circuits.
A new memory requires the formation of a memory trace, or "engram", in the brain. First, the hippocampus and other nearby cortical areas are thought to integrate sensory inputs into a cohesive representation. Then, memory is stored more permanently through connections with other parts of the brain including the neocortex. A major mechanism through which circuits of the brain can learn is through long-lasting increases (or decreases) in the strength of synaptic connections between neurons. My lab examines how changes in synaptic strength occur in parahippocampal and neocortical regions of the rat. Electrophysiological recording techniques are used to monitor synaptic strength and to examine how neuromodulatory systems (cholingergic, dopaminergic) and rhythmic EEG activities control changes in how neurons interact with one another.
Both graduate and undergraduate students make important contributions to this research. Please contact me if you are interested in conducting an Honours thesis, Specialization project, or Science College project in the lab.
My research is funded by the Natural Sciences and Engineering Research Council (NSERC) Discovery Grant program.

Eleanor Bond, aCanadian artist based in Winnipeg and Montreal, is known for adistinctive body of paintings and drawings that combine speculativeprojections of the built environment with meditations on a number ofsocial, ecological, political and economic themes. For the past decade,the research and interpretation of particular cities, such asRotterdam, Salzburg and Detroit, has been central to her practice. Bondhas exhibited internationally since 1987, with major showings at theMuseum of Contemporary Art in Sao Paulo, Witte de With in Rotterdam,the Clocktower in New York and the Museum of Contemporary Art inMontreal, and others. Her most recent exhibitions were in Tokyo, Seoul,Hamilton and Berlin.
