Pre-excitatory pause in frontal eye field responses.
We report a new characteristic of the presaccadic activity of the neurons in the frontal eye field of macaque monkeys. A fraction of neurons exhibited a significant pause in discharge rate preceding the excitatory visual or movement-related response. This pre-excitatory pause, which has been observed in striate and extrastriate visual areas, may represent a resetting of neural activation for detailed visual processing or saccade preparation.
