Centre for Cognitive science and intelligence technology is interested in the brain mechanisms underlying visual cognitive functions such as visual attention, perception, working memory and eye movement etc. Impairments in these mechanisms have been associated withbrain disorders such as ADHD, autism and schizophrenia. By studying the visual systems in nonhuman primates, we have shown that visual attention is mediated by complex interactions between association cortex, visual cortex and sub-cortex areas. Our long-term research goal is to characterize the mechanisms underlying these inter-area communications and local interactions within an area, then apply this scientific knowledge to help to understand the mechanisms of brain disorders. We use a multi-disciplinary approach, including electrophysiology, behavior, optogenetics, neuronal imaging to study these questions in alert monkeys.
