Basal ganglia  (basal  nuclei) are several pockets  of gray matter located  deep inside the cerebral  white matter. The major  regions in the basal  ganglia—the caudate  nuclei, the putamen, and  the globus pallidus—are  involved in relaying and  modifying nerve impulses  passing from the cerebral  cortex to the spinal cord.  Arm swinging while

walking, for example, is  controlled here. The diencephalon connects  the cerebrum to the brainstem. It  consists of the following major  regions: The thalamus is a relay  station for sensory nerve  impulses traveling from the  spinal cord to the  cerebrum. Some nerve  impulses are sorted and  grouped here before being  transmitted to the  cerebrum. Certain

sensations, such as pain,  pressure, and sensitivity to  temperature, are also  evaluated here. The epithalamus  contains the pineal gland.  The pineal gland secretes  melatonin, a hormone that  helps regulate the  biological clock (sleep- wake cycles). The hypothalamus  regulates numerous  important body activities. It  controls the autonomic
