Storage of Information — Memory Only a small fraction of even the most important sensory
information usually causes immediate motor response. But much of the information is stored for future
control of motor activities and for use in the thinking processes. Most storage occurs in the cerebral cortex, but even the basal regions of the brain and the spinal cord can storesmall amounts of
information.
Major Levels of Central Nervous System Function The human nervous system has inherited special functional capabilities from each stage of human
evolutionary development. From this heritage, three major levels of the central nervous system have
specific functional characteristics:
(1) the spinal cord level, (2) the lower brain or subcortical level, and (3) the higher brain or
cortical level.
