Pre-movement cortical potentials related to spontaneous, reflex and voluntary blinks were studied in normal subjects. Blinks performed at will were found to be prefaced by a bilateral negative cortical potential, whereas spontaneous and reflex blinks were not. The data support the hypothesis that only volitional motor acts require a cortical participation; spontaneous and reflex blinking are probably organized only at a subcortical level.
