Description: The NIH Director's Wednesday Afternoon Lecture Series

Although parietal cortex has been implicated in the neural processes underlying visual attention since the 19th century, the nature of its contribution has not been well understood. I will describe a new method to track the temporal and spatial dynamics of attention in the monkey, using the attention evoked by the plan to make an eye movement to a point in the visual field, and the attention evoked by a distractor in another part of the visual field. I will then show how the activity of neurons in the lateral intraparietal area (LIP) correlates with the monkey’s attentional performance, even to predicting how long the monkey's attention moves in time and and space, and even how long it will dwell on the distractor.
