In Experiment 1 unilateral injection of the GABA agonist, muscimol (20 ng in 0.1 microliter saline) into the substantia nigra (SN) of rats elicited contraversive turning and a correlated transient asymmetry in responsiveness to tactile stimulation of the mouth area. On the side of the face contralateral to the injected SN they responded stronger than on the ipsilateral side, and, furthermore, they responded to tactile stimulation with a withdrawal of the lip, followed by a vigorous biting of… CONTINUE READING
