Abstract
Rats with lesions of the occipital pole or a more anterior extrastriate area were tested on either original learning of a successive brightness discrimination or retention of this task after acquisition as a normal. Equivalent original learning losses relative to normals were sustained from both lesions, but while extrastriates showed substantial savings in retention, rats with occipital pole damage required as many relearning trials as were necessary for original learning by brain-damaged groups. It was suggested that the effect of the anterior extrastriate lesion was to impair a spatial or positional component of discrimination performance, and that this component might differ from one related to visual task properties, especially in terms of recovery of function following brain damage.
