title: Activity of neurons in the lateral intraparietal area of the monkey during an antisaccade task.
abstract: The close relationship between saccadic eye movements and vision complicates the identification of neural responses associated with each function. Visual and saccade-related responses are especially closely intertwined in a subdivision of posterior parietal cortex, the lateral parietal area (LIP). We analyzed LIP neurons using an antisaccade task in which monkeys made saccades away from a salient visual cue. The vast majority of neurons reliably signaled the location of the visual cue. In contrast, most neurons had only weak, if any, saccade-related activity independent of visual stimulation. Thus, whereas the great majority of LIP neurons reliably encoded cue location, only a small minority encoded the direction of the upcoming saccade.
