Effects of electroconvulsive shock on maze relearning by albino rats.

Abstract

After 40 one per day trials on a 13-unit water maze, a 40-day rest was given. Experimental animals were given one ECS per day the last 10 days of the rest interval and the first 10 days of a 25-day retention and relearning period. The ECS group showed marked inferiority in retention and re-learning up to four days after cessation of the shock period.
