Comparison of reward modulation in the frontal eye field and caudate of the macaque.
The frontal eye field (FEF) influences saccade generation via direct projections to the superior colliculus and an indirect pathway through the basal ganglia. To test whether different reward information is represented in the FEF and the basal ganglia, we recorded from the FEF and the caudate nucleus in monkeys performing an asymmetrically rewarded memory-guided saccade task. A peripheral cue a...
متن کاملFrontal eye field contributions to rapid corrective saccades.
Visually guided movements can be inaccurate, especially if unexpected events occur while the movement is programmed. Often errors of gaze are corrected before external feedback can be processed. Evidence is presented from macaque monkey frontal eye field (FEF), a cortical area that selects visual targets, allocates attention, and programs saccadic eye movements, for a neural mechanism that can ...
متن کاملDisparity sensitivity of frontal eye field neurons.
Information about depth is necessary to generate saccades to visual stimuli located in three-dimensional space. To determine whether monkey frontal eye field (FEF) neurons play a role in the visuo-motor processes underlying this behavior, we studied their visual responses to stimuli at different disparities. Disparity sensitivity was tested from 3 degrees of crossed disparity (near) to 3 degree...
متن کاملThe responses of visual neurons in the frontal eye field are biased for saccades.
Previous research suggests that visually responsive neurons in the frontal eye field (FEF) respond to visual targets even when they are not the goal of a saccadic eye movement. These results raise the possibility that these neurons respond to visual targets independent of the effector that is to be used to acquire the target locations. In the present study, we examined whether a plan to execute...
متن کاملCaudate encodes multiple computations for perceptual decisions.
Perceptual decision making is a complex process that requires multiple computations, including the accumulation of sensory evidence and an ongoing evaluation of the accumulation process to use for prediction and adjustment. Implementing these computations likely involves interactions among many brain regions. For perceptual decisions linked to oculomotor actions, neural correlates of sensory ev...
