 Fig. 13. Effect of cathodal (A) and anodal (B) polarization on learning curves 

 in two additional animals. Explanation in text. 



corresponds closely to that occurring after a lapse in training. 

 It would appear that training under conditions of cathodal polari- 

 zation of visual cortex did not result in registration or retention 

 of that day's experience. The animal behaved as though there 

 had been no training at all on that day. 



Figures 12B and 13B present curves of the typical response 

 pattern in two animals subjected to bilateral anodal polarization 

 of motor cortex, visual cortex and the ear. There is no evidence
