Abstract

We studied the eye movements (EM) elicited by electrical stimulation of the frontal lobe in 19 awake patients evaluated with subdural electrodes for epilepsy surgery. All patients had only contralateral conjugated EM. They were saccadic in 16 patients (84%). Head version, always following the eye deviation, occurred in 11 patients (58%). We also determined the eye field somatotopic distribution analyzing the responses obtained from the electrodes adjacent to the eye fields. All patients had motor cortex contiguous to the eye fields. In 17 patients (90%) the eye fields were located in front or at the level of the motor representation. There was no silent cortex between the motor strip and the eye fields.
