✦ Synopsis

In an earlier paper (Larsson, '62) it was reported that bilateral lesions in the lateral parieto-temporal area of the cerebral hemispheres have more severe effects upon the mating behavior of male rats than injury to the medial parts of the frontal, parietal, and occipital lobes. Whereas lateral lesions permanently eliminated mating in several of the animals and lowered the activity of others, removal of the median cortex in no case did permanently abolish sexual behavior. In the present study an attempt has been made to localize the critical area by removing either the anterior or the posterior part of the dorsolateral surface.
