  3. peripheral nervous system (PNS)
  4. association areas
  5. fMRI (functional magnetic resonance imaging)
  1. a areas of the cerebral cortex that are primarily involved in higher mental functions such as learning, remembering, thinking, and speaking.
  2. b the sensory and motor neurons connecting the central nervous system (CNS) to the rest of the body.
  3. c a technique for revealing bloodflow and therefore, brain activity by comparing successive MRI scans. show brain function.
  4. d chemicals, such as opium, morphine, and heroin, that depress neural activity, temporarily lessening pain and anxiety.
  5. e neuron extensions that receive messages and conduct impulses toward the cell body.

5 Multiple choice questions

  1. the biological clock; regular-bodily rhythms (for example, of temperature and wakefulness) that occur on a 24-hour cycle.
  2. portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgments.
  3. a neural structure lying below the thalamus; directs several maintenance activities (eating, drinking, body temperature), helps govern the endocrine system via the pituitary gland, and is linked to emotion.
  4. our awareness of ourselves and our environment.
  5. a neuron's reaction of either firing (with a full-strength response) or not firing.

5 True/False questions

  1. motor cortexarea at the rear of the frontal lobe; controls voluntary movements.

          

  2. sensory cortexthin layer of interconnected neurons covering the cerebral hemispheres; the body's ultimate control and information-processing center.

          

  3. split braincondition in which the brain's two hemispheres are isolated by cutting the fibers (mainly those of the corpus callosum) connecting them.

          

  4. autonomic nervous systemthe division of the peripheral nervous system that controls the glands and the muscles of the internal organs (such as the heart). Its sympathetic division arouses; its parasympathetic division calms.
