| Research Abstract |
Functionally, the suppression of eye movements is essential during visual fixation to hold the image of the target on the fovea(selective attention). In the present study, we identified a localized area in the monkey frontal eye field(FEF) at which electrical stimulation induced suppression of the initiation of saccades bilaterally at low thresholds. This area was also associated with the suppressive effect of stimulation on smooth pursuit eye movements, suggesting that the suppressive control of saccades and pursuit may be exerted by a common neuronal assembly in the FEF.
