EFFECTS OF LESIONS TO CORPUS STRIATUM UPON SPONTANEOUS ACTIVITY IN THE MALE RAT

Abstract

Spontaneous activity of 5 [male] rats was measured in revolving cages for 30 days before and 50 days after electrolytic destruction of varying amounts of the corpus striatum. Activity increased postoperatively in 1 animal, decreased in 2, and was unchanged in 2 others. No relationship between magnitude of lesion and effects upon activity could be detd. In the rat the striatum evidently does not exert a controlling effect upon running activity as measured in the present expt.
