“…Similarly, shocked animals that are allowed sufficient time to eat to permit them to maintain weight and exhibit some daily gain would be less hungry than controls and therefore perform less well. However, the water-maze behavior of the convulsed rat (2,3) indicates that shock also acts to produce a deficit in perform-ance that is independent of hunger. This would suggest that in addition to its effect on hunger drive, shock also affects motivation to escape from water.…”

Many studies have used food-motivated maze running to assess the effects of electroconvulsive shock (ECS) on learning and retention. These studies have generally assumed that an impaired maze performance results only from the effects of the shocks on the cerebral functions subserving learning and retention. However, if hunger drive is decreased as a result of shock, an impairment in performance may occur independently of the cerebral effects. That hunger drive may indeed be affected is suggested in the studies of Bernberg (1) and Jensen and Stainbrook (6), who report alterations in the eating behavior of the rat following a series of ECS's. Neither of these studies, however, was designed specifically for the purpose of investigating the effect of ECS on hunger drive.The study reported here did so, two chief considerations determining the experimental plan. First, since Miller, Bailey, and Stevenson (8) had demonstrated that in rats with lesions in the hypothalamus increased food intake is associated with decreased hunger drive, and since Hoyt and Rosvold (5) had implicated the hypothalamus in the effects of ECS, it was necessary to measure separately the effects of ECS on food intake and hunger drive. Second, ECS in the rat results in decreased activity which may affect eating in two ways: an inactive animal requires less food; the activity of consuming food may be subject to the same reduction as is spontaneous locomotion. Therefore, activity measures were made coincident with the measures of eating behavior. METHOD AnimalsTwenty-two 160-day-old male albino rats of the Sprague-Dawley strain were housed individually either in separate cages or in activity wheels. They were weighed and then fed at the same time each morning

“…The ECS scries consisted of giving each of the rats in the shock group one ECS per day for 10 days, or for 25 days in the second study. The procedure for administering the ECS was similar to that described by Braun, Russell, and Patton (2). A current of 20 Ma.…”

Investigation of the effects of the age of the rat when it begins a series of electroshock convulsions upon the relative amount and duration of subsequent behavioral impairment is needed to help clarify the factors which influence postconvulsive behavior in the rat, and thus to contribute to a theory of such behavior. Various hypotheses have been advanced (4, 5) concerning the effects of age at the time of convulsive treatment in the rat, but only Hayes (5), to this writer's knowledge, has published relevant data, and this was incidental to his primary experimental concern.
