Bio Psych 3 & 4
Show Answers:

  1. Processes the skin senses and detects body movement and position
    Somatosensory cortex
  2. Helps the person identify objects by touch, determine the location of the limbs, and locate objects in space
    Association cortex
  3. The primary projection area for hearing
    Auditory cortex
  4. Invovled in language projection area for hearing
    Wernicke's area
  5. Recieves information from all sensory systems except smell
  6. Plays a major role in controlling hormone function, emotion and motivated behaviors
  7. Involved in daily rythms in humans
    Pineal gland
  8. A dense band of fibers connecting the two hemispheres. Shares information between the two hemeispheres
    Corpus Collosum
  9. Feeds the brain and takes away waste
  10. Responsible for life function (e.g. - breathing, heart)
  11. Contains sensory pathways and center relates to sleep and arousal
  12. Controls the speed, intensity and direction of motor movements and may also play a role in motor learning, cognitive processes and emotion
  13. A cable of neurons and axons that carries information from the brain to the muscles and organs, and sensory information to the brain
    Spinal Cord
  14. Encloses the brain and spinal cord
  15. limits the passage of toxins and neurotransmitters between the brain and the bloodstream
    Blood-brain barrier
  16. Composed of cranial and spinal Nerves
    Peripheral Nervous system
  17. Operates the muscles of the body and the sensory neurons that bring information into the central nervous system
    Somatic Nervous system
  18. Regulates general body activity and internal activity
    Automatic Nervous system
  19. Responsible for arousal to cope with demands
    Sympathetic nervous system
  20. Responsible for reducing arousal and restoring energy, e.g. - activating digestion
    Parasympathetic nervous system
  21. the ability of neural systems to be modified
  22. Occurs early in life, and is the birth and division of new neurons
  23. The regrowth of severed axons, does not occur in the mammalian CNS
  24. Occurs when uninjured tissue takes over the functions of neuron lost to injury
  25. The birth of new neurons, occurs only in the hippocampus and near the lateral ventricles
  26. An imaging neural tissue that makes it possible to visualize neurons, glia and connection in the brain
  27. Randomly stains a small number of neurons
    Golgi stain
  28. identify connections by staining the fatty insulation on axons and dendrites
    Myelin stains
  29. Identify neuron cell bodies
    Nissal stains
  30. Reveals both neuronal anatomy and function
  31. Antibodies are labeled with markers and attach to receptors on neurons
  32. Uses electrons for much higher magnification, but requires a computer to visualize specimens
    Electron microscopy
  33. Probes a specimen with an electron beam, causing it to emit electrons to form a detailed picture of the object
    Scanning electron microscope
  34. Detects electrical activity of the brain through electrodes placed on the scalp
    Electroencephalography (EEG)
  35. Rely on thousands of stimulus presentations to cancel out background and reveal meaningful changes in the brain activity
    Evoked potentials
  36. Instrument and atlas that enables precise location of brain areas for stimulation or measurement
  37. Record or stimulate the brain electrically
  38. The removal of nervous tissue
  39. Provides a 3-D picture of the brain and body
    Brain imaging technique
  40. A machine that measures brain activity as well as anatomy, but are expensive and not as fast
    Functional magnetic resonance imaging (fMRI)
  41. Measures radio frequecny waves emitted by hydrogen atoms, subjected to a strong magnetic field
    Magnetic Resonance Imaging (MRI)
  42. Uses X-rays to visualize the brain. Fast but low resolution
    Computed Tomography (CT)
  43. Determines how strongly a trait is shared among relatives
    Family studies
  44. The frequency with which relatives are alike
    Concordance rate
  45. Technique that inactivates a gene by placing a mutation in the gene which prevents it from functioning
  46. The treatment of disorders through manipulating genes
    Gene therapy
  47. the injection of undifferentiated cells into a damaged brain (or other area) in the hopes that the cell will develop into appropriate tissue (such as neurons) and restore fucntion
    Stem cell therapy
