Eye movements following cortical stimulation in the ventral bank of the anterior ectosylvian sulcus of the cat.
Eye movements were induced by stimulating the ventral bank of the anterior ectosylvian sulcus (AES) of chloralose-anesthetized cats. Intracortical microstimulation of this cortex evoked centering movements of both eyes. The latency of eye movement was 45 ms (range 40-60 ms) and the intensity of stimulation was 33 microA (range 20-45 microA). The evoked eye movements persisted after ablation of the classical frontal eye field of both sides. These results suggest that the ventral bank of the AES is involved in the control of eye movements.
