Frontopolar rats performance in Dashiell maze

Frontopolar and unoperated control rats were given two or five trials for 20 days in Dashiell maze. Both groups made a negligible number of errors and showed considerable preference for peripheral paths. No marked differences were found in number of perseverative responses, number of different paths chosen and number of shifts between paths. The findings indicate that frontopolar lesion does not increase the perseverative tendency in a situation involving no difficulty in choice behavior. This lesion also does not affect the directional orientation.
