Electroencephalographic features of the blind in response to several planned stimulations.
EEG records were obtained from 9 blinds under several types of stimulation. The occipital alpha rhythm was much reduced in them, whereas small parietal activity in the alpha range was often observed in the later blind. Any type of stimulation did not produce beta rhythm, but accelerated the background alpha rhythm.
