Document Summary
How the brain produces both behaviour and human consciousness are major unanswered scientific questions. The brain is the most complex living organ on earth and is found in most animals. Many behavioural disorders can be explained and possibly treated as we increase our understanding of the brain. Brain: anglo-saxon word for the tissue found within the skull. Cerebral cortex heavily folded outer layer of brain tissue: gyri bumps on the folded surface, sulci grooves of the cortex. Most of the connections between the brain and the rest of the body are made through the spinal cord: spinal cord part of the central nervous system encased within the vertebrae (spinal column) The brain and spinal cord make up the central nervous system (cns) All of the processes radiating out beyond the brain and spinal cord constitute the peripheral nervous system (pns)
