Dr. Wong, an Assistant Professor at McGill University and a researcher at the Douglas Mental Health University Institute, is interested in understanding the impact of stress on the brain. He also evaluates how this relates to individual behaviour, learning ability, and memory formation. One of his research interests is that of understanding how stress produces an abnormality in synaptic transmission and, consequently, impairment in memory formation. Using a combination of electrophysiological, molecular, and proteomic approaches, he will study the molecular mechanism of how stress facilitates a form of hippocampal synaptic plasticity, namely, long-term depression (LTD). Another major direction of Dr. Wong’s laboratory is that of studying the molecular mechanisms of synaptic plasticity, a cellular process that regulates the strength of synaptic transmission. Research in synaptic plasticity has recently evolved from a focus on physiological processes such as learning and memory to its potential pathological role in producing abnormal synaptic transmission, which is the most common neuropathology in mental illness. For instance, Dr. Wong and his colleagues have found that formation of LTD is greatly affected in animal models of schizophrenia. Understanding how LTD is affected in these animal models could reveal therapeutic targets for treating synaptic pathologies in schizophrenia.
