Male hooded Long-Evans rats subjected to a 2-stage removal of the posterior or anterior isocortex retained a black-white habit no better than 1-stage bilateral controls. Amphetamine injections combined with light and dark housing conditions during the interoperative interval also failed to yield savings. 2 experiments suggest that successive procedures which do not involve interoperative training are unlikely to produce improved retention of a black-white habit.
