Abstract

Subjects with congenital deficits that allowed only diffuse light perception through one eye were examined for blocking of the alpha rhythm. With only the deprived eye open the electroencephalogram is dominated by alpha rhythm that is not blocked by photic stimulation, even though the stimuli evoke a response from occipital cortex.
