Cortical Evoked Potentials by Photic Stimulation at Variousadaptation Levels of Retina in Man.

Monnier,l-3) Cobb,4,5) Ciganek,6,8) Balen and Henkes,9,10) Laue,11.12), Calvet, Contamin and Hirsch et al.13-15) have studied on photically evoked potentials of the visual cortex in man, and thus at the present time physiological and anatomical correlation of the evoked potential to the visual cortex is being elucidated step by step by the method of evoked potentials and other physiological methods. In our previous paper16) the changes of the evoked potential depending upon the intensity of photic stimulation were reported. In the present paper the results of similar experiments carried out under light adaptation of various levels will be reported.
