My current research is focused on the mechanisms underlying processing and storage of visual motion information in primate cortex. In our studies we combine single cell recordings, microstimulation, reversible inactivation with psychophysical measures of visual performance. We have shown that neurons in visual cortical area MT, strongly associated with processing of visual motion, also participate in the storage and the retrieval/comparison operations required by working memory tasks.
