Neuroscientists want to unify the science of the mind with the science of the brain. Actions of the brain underlie all behavior. What we call mind is a range of functions carried out by the brain. More intelligent animals have increased uncommitted or association areas of the cortex. Cns: central executive where decisions are made. Pns: provides cns with info from sensory receptors and relays commands from the brain to the body"s organs and muscles. Where muscles are moved, internal organs are regulated, and sensory input is moved toward the brain. Pns: composed of 2 sets of nerve fibers. Somatic nervous system: regulates actions of the body"s skeletal muscles. Delivers information about the environment to the brain. Autonomic nervous system: controls the more automatic functions autopilot (dual system] Deals with survival matters of 2 kinds: threats to the organism, bodily maintenance. Rests atop and connects to spinal cord. Subcortical structures deep in the interior.
