Dr. Leung plans to admit a new graduate student pending approval of funding.

Research Interests:

Cognitive neuroscience, spatial working memory, action control, eye movement control, neuroimaging.

Current Research:

Dr. Leung's primary research interest is in understanding the neural basis of cognitive processes, with particular emphasis on the contribution of the prefrontal cortex. In the past, I studied the activity of the prefrontal cortex and other cortical areas during cognitive interference and visual-spatial working memory using functional magnetic resonance imaging (fMRI). Current research continues on investigating the functional organization of the human prefrontal cortex and its interaction with posterior association areas and subcortical areas. We are studying the human prefrontal circuits during processing different forms of visual information and its role in recognition/response selection using fMRI. The lab is also interested in understanding the relationship between the abnormalities of the prefrontal cortex and cognitive dysfunctions observed in patients with psychiatric and neurological disorders.
