ResumoThe monkey frontal eye fields contain cells which perform a spectrum of oculomotor-related activities. For example, there are three types of cells involved in presaccadic activity; visual cells that are often enhanced when visual stimuli are used as saccade targets, movement cells that discharge before purposive (but not spontaneous) saccades, and visuomovement cells that discharge best or solely before visually-guided saccades. Electrical stimulation at a given site in the frontal eye fields evoke saccades that are very similar, both in amplitude and direction, to the saccades associated with maximal presaccadic activity at that site. We conclude that the physiology of monkey frontal eye fields corroborates the classical hypothesis that this cortex participates in the initiation of voluntary eye movements.
