The lab’s R01 grant got renewed in March and will fund the lab for the next few years. Much thanks to NIH’s National Eye Institute for their continued support of our lab’s work.
The goal of the proposed work is summarized below:
Despite the widespread appreciation that the prefrontal and posterior parietal cortices (PFC/PPC) are necessary for flexible action and efficient perception, there is a fundamental gap in understanding the control mechanisms by which they accomplish these goals. This gap in knowledge is a critical problem because a host of psychiatric and neurologic disorders stem from a primary dysfunction of executive control. The long-term goal is to understand the mechanisms by which the PFC and PPC exert control over motor and sensory systems. The objective of the current proposal is to test models of how activity in the PFC and PPC form maps of prioritized space that tag salient and relevant locations in the visual field, which can then be used as the basis of executive control signals. The mechanisms of bias are likely to involve mechanisms used for saccade planning.
