Abstract Two series of experiments were performed in cats in which 80 Μg of atropine in 5 Μl were injected into the head of both caudate nuclei. In order to obtain a reward (a constant amount of milk) the first group of Ss learned to walk a distance of 75 cm after the delivery of 4 flashes, while the second group learned to press a lever. Both tasks were significantly impaired (P〈0.05) after atropine injection. The motor reflex response as well as hunger motivation were not modified by the substance. A caudate-cholinergic mechanism involved in the maintenance of motor conditioned responses is proposed.
