Difference patterns of k* responses to quinpirole and carbamazepine in sagittal representation of rat brain. Regions in which k* was increased significantly (P < 0.05) compared with chronic vehicle + saline are solid black, regions in which k* was decreased significantly are hatched. List of regions: A, amygdala; Acb, nucleus accumbens; Aud, auditory cortex; av, anteroventral thalamic nucleus; CbG, cerebellar gray matter; CbW, crebellar white matter; CPu, caudate putamen; DLG, dorsal lateral geniculate nucleus; Fr, frontal cortex; GP, globus pallidus; HB, habenular nuclei; HIP, hippocampus; HYP, hypothalamus; IC, inferior colliculus; IPC, interpeduncular nucleus; MM, mammillary nucleus; mG, medial geniculate nucleus; MolCBG, molecular layer of cerebellar gray matter; Mot, motor cortex; OT, olfactory tubercle; PF, prefrontal cortex; pt, paratenial thalamic nucleus; SN, substantia nigra; S, septum; SS, somatosensory cortex; SC, superior colliculus; SCgl, gray layer of superior colliculus; STH, subthalamic nucleus; THa, thalamus; Vis, visual cortex
