Mice received a single training trial on an inhibitory avoidance task and a retention trial 24 hours later. Electroshock stimulation, administered 25 seconds after the training trial, produced amnesia even if the convulsion was prevented by ether anesthesia. The amnesia produced by such shock is apparently due to the electric current and not to the convulsion.
