Document Summary
How the brain produces behaviour is a major unanswered scientific question. The brain is the most complex living organ on earth and is found in many groups of animals. A growing list of behaviour disorders can be explained and treated as we increase our understanding of the brain. Central nervous system (cns): made up of the brain and the spinal cord (which descends from the brainstem through a canal in the backbone) Encased in bones, the brain by the skull and the spinal cord by the backbone or vertebrae. Central because is physically the nervous system"s core and is also the core structure mediating behaviour. Peripheral nervous system (pns): all of the processes radiating out beyond the brain and spinal cord. Neurons and nerve processes outside cns, neurons being the cells that compose the human nervous system and the rest of the body, controls behaviour. Cerebrum: the forebrain, made up of two hemispheres, responsible for most of our conscious behaviours.
