Abstract

A revolving food pellet (RFP) test is presented, measuring the ability of rats to eat food pellets suspended from a horizontal bar in theirhome cage. This easy to make and economical device evaluates the efficiency of bilateral front paw coordination while standing. During the beginning of a ten day testing period, rats exposed to the RFP chamberhad a lower intake of food and decreased body weight than rats housedin a standard home cage. With continued practice, the experimental group increased their food intake and body weight. During this time, therats learned to control the revolving pellets by stabilizing them with their front paws and chewing on them. This apparatus is suitable forassessing a form of sensorimotor learning, involving the efficiency of front paw reaching, grasping, and holding movements, together with appropriate postural adjustments and biting movements. This test was sensitive to brain lesioning, as rats with bilateral lesions of the cerebellar fastigial nucleus were impaired. (C) 1997 Elsevier Science B.V.
