Abstract
A learned brightness discrimination that would be lost following a bilateral posterior neocortical lesion in rats (Ns = 64 in Exp. I and 74 in Exp. II) can be spared if the tissue is removed in 2 successive unilateral operations. If the lesion involves about 10% of the total neocortex nonspecific visual stimulation is sufficient to obtain sparing; if the lesion involves about 20% of the total neocortex specific practice of the habit is necessary.
