Short-duration stimulation of the supplementary eye fields perturbs anti-saccade performance while potentiating contralateral head orienting.
Many forms of brain stimulation utilize the notion of state dependency, whereby greater influences are observed when a given area is more engaged at the time of stimulation. Here, by delivering intracortical microstimulation (ICMS) to the supplementary eye fields (SEF) of monkeys performing interleaved pro- and anti-saccades, we show a surprising diversity of state-dependent effects of ICMS-SEF...
متن کاملRecruitment of a contralateral head turning synergy by stimulation of monkey supplementary eye fields.
The supplementary eye fields (SEF) are thought to enable higher-level aspects of oculomotor control. The goal of the present experiment was to learn more about the SEF's role in orienting, specifically by examining neck muscle recruitment evoked by stimulation of the SEF. Neck muscle activity was recorded from multiple muscles in two monkeys during SEF stimulation (100 μA, 150-300 ms, 300 Hz, w...
متن کاملSupplementary eye fields stimulation facilitates anticipatory pursuit.
Anticipatory movements are motor responses occurring before likely sensory events in contrast to reflexive actions. Anticipatory movements are necessary to compensate for delays present in sensory and motor systems. Smooth pursuit eye movements are often used as a paradigmatic example for the study of anticipation. However, the neural control of anticipatory pursuit is unknown. A previous study...
متن کاملSupplementary Eye Fields
The supplementary eye fields (SEFs) are located in dorsomedial frontal cortex and contribute to high-level control of eye movements. Recordings in the SEF reveal neural activity related to vision, saccades, and fixations, and electrical stimulation in the SEF evokes saccades and fixations. Inactivations and lesions of the SEF, however, cause minimal oculomotor deficits. The SEF thus processes i...
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...
