AUTO- AND CROSS-CORRELATION OF FOREBRAIN ELEC TRICAL POTENTIALS EVOKED BY SENSORY AND OTHER INPUT.

Abstract

A computer system which averages repetitive evoked potentials and which conducts a variety of other operations has been developed, assembled, and improved. The computer is used to investi gate electrophysiological potentials and to con duct a series of mathematical and statistical operations. The apparatus is used in the study of normal and defective subjects. With it evoked potentials have been studied in patients with lesions in the visual system. In favorable cases post retinal and retinal lesions can be localized. With normal subjects the apparatus has been applied to basic studies of the visual system to obtain light adaptation data for comparison with psychophysics. It has also been used in a number of other projects which are concerned witthe quality of the retinal image, vigilance, sleep and wakefulness, the EEG, and learning. New pro grams which greatly enhance its value continue to be developed. (Author)
