Electrical stimulation of the frontal eye fields in the head-free macaque evokes kinematically normal 3D gaze shifts.
The frontal eye field (FEF) is a region of the primate prefrontal cortex that is central to eye-movement generation and target selection. It has been shown that neurons in this area encode commands for saccadic eye movements. Furthermore, it has been suggested that the FEF may be involved in the generation of gaze commands for the eye and the head. To test this suggestion, we systematically sti...
متن کاملElectrical stimulation of the supplementary eye fields in the head-free macaque evokes kinematically normal gaze shifts.
The supplementary eye fields (SEFs), located on the dorsomedial surface of the frontal cortex, are involved in high-level aspects of saccade generation. Some reports suggest that the same area could also be involved in the generation of motor commands for the head. If so, it is important to establish whether this structure encodes eye and head commands separately or gaze commands that give rise...
متن کاملContribution of the frontal eye field to gaze shifts in the head-unrestrained monkey: effects of microstimulation.
The role of the primate frontal eye field (FEF) has been inferred primarily from experiments investigating saccadic eye movements with the head restrained. Three recent reports investigating head-unrestrained gaze shifts disagree on whether head movements are evoked with FEF stimulation and thus whether the FEF participates in gaze movement commands. We therefore examined the eye, head, and ove...

متن کاملIntracortical microstimulation of bilateral frontal eye field.
We trained two monkeys to perform a fixation task. Intracortical microstimulation (ICMS) was applied to the monkey frontal eye field (FEF) while monkeys were fixating on one of five fixation LEDs. The ICMS was applied in two different manners. Under the single stimulation condition, ICMS was delivered to either right or left FEF. Under the paired stimulation condition, bilateral FEF were succes...
