Delayed responses of the kinesthetic type following frontomedial lesions in rats.
Returning behavior was tested before and after frontomedial surgery. In this test rats had to go for food and return to the starting place by the same route in an elevated T maze. The correct return response required the immediate retention of the turn performed on the way to food. Subtotal, although considerably large lesions of the frontomedial cortex, had no effect on performance. Lesions covering almost the entire area between the tip of the pole and genu of the carpus callosum decreased performance almost to the chance level, and no improvement was observed during 30 sessions.
