FAST POSITIVE POTENTIALS OF THE HUMAN BRA IN CORTEX TO VISUAL-STIMULIWHICH INDUCE SACCADES

The EEG was recorded in 7 healthy subjects aged 20-25 years according to the International 10-20 System in the frontal and parietal derivati ons (F3, F4, Pz, P3, P4) during the saccades related with the visual s timuli. A complex of fast (positive and negative) event-related potent ials was recorded in response to visual stimulation before the saccade onset. The amplitude and spatial distribution of these potentials dep ended on the saccade latency, order of stimuli presentation, personali ty of a subject etc. The results suggest that the early positive poten tials observed in the saccade latent period reflect the activation of the cortical structures which participate in programming and initiatio n of saccades.
