  19. -the rest of the brain that covers the central core
    -a part of the brain that covers the brains central core consists of left and right hemispheres which are connected by a wide band of fibers the corpus callosum
  20. the differnt regions into which the cerebral cortex is divided
    Ex: occipatal lobe- vision
  21. -measures brain activity
    -a machine used to record the electrical activity of large portions of the brain
    Ex: activity of neuron when sleeping
    electroencephalograph (EEG)
  22. -shows brain stucture
    -X-ray of brian
    -an imaging technique used to study the brain to pinpoint injury and brian deterioration
    Ex: when you get hit by a football
    computerized axial tomography (CAT)
  23. -patients drink radio active glucose and image shoes areas of brain activity
    -an imaging technique used to see which brain areas are bieng activated while performing tasks
    Ex: when speaking or thinking
    position emmision tomography (PET)
  24. An imaging technique used to study brain structure and activity
    Ex: to view the brain
    Magnetic resonace imaging (MRI)
  25. a chemical comunnication system using horomones by which messages are sent through the bloodstream
    Ex: horomones/ bloodstream body fluids
    endocrine system
  26. chemical substances that carry messages through the body in blood
    Ex: pituitary gland adrenal medulla
  27. the center control of the endocrine system that secretes a large number of hormones
    Ex: master gland/ Growth
    pituitary gland
  28. -located in the hind brain
    -helps control posrture balance voluntary movements
  29. -located in the hind brain
    -function as bridge from brain to spinal cord
    -produces chemical for sleep
  30. -located in the hindbrain
    -controls breathing, heart rate, & a veriety of reflexes
  31. -located in the midbrain
    -intergrates sensory information and relays it upwards
    -serves to alert the rest of the brian to incoming signals and is involved in the sleep/wake cycle
    retcular activating system (RAS)
  32. -located in the forebrain
    -intergrates sensory input, relay station for all information from the cortex
  33. -located in the forebrian
    -controls hunger, thirst, sexual behavior, body reactions to change in temp
  34. -located in the forebrain
    -ability to learn & store complex & abstract information project, our own thinking to the future
    cerebral cortex
  35. -located in the forebrain
    -controls sight of conscious thinking process

    -regulates emotion and motavation
    limbic system
  37. -located in the forebrain
    -controls emotions
  38. -located in the very rear
    -is for vision
    occipital lobe
  39. -mid way between front and rear
    -deals with body sensation
    parietal lobe
  40. -located in the front of brian
    -planning of movements, working movements, working memory, organization, planing & creative thinking
    frontal lobe
  41. -located on the side of brain
    -deals with hearing
    temporal lobe
  42. process info wholistically look at the big picture not details
    -random jump task task
    -decision are based on feelings
    -know what you mean but might have difficulty expressing it
