Psychosurgeries like lobotomy - Intro to Psychology

  • 0:00 - 0:05
    Now we just finished talking about drug therapy as a biological treatment. So
  • 0:05 - 0:08
    lets move on to the second major area of biological treatment and that is
  • 0:08 - 0:12
    psychosurgery. Psychosurgeries involve medical procedures on the brain in an
  • 0:12 - 0:17
    attempt to alleviate the symptoms of psychological disorders. Now the first
  • 0:17 - 0:21
    psycho-surgery going to discuss was actually widely over-used, and had tragic
  • 0:21 - 0:27
    consequences including sometimes death. This is the pre-frontal lobotomy. The
  • 0:27 - 0:31
    lobotomy involved cutting the connection between the pre-frontal cortex and the
  • 0:31 - 0:36
    lower area of the brain. Now this technique is no longer used today. But if you
  • 0:36 - 0:40
    think back to the material on lesson three in the brain and behavior, you'll
  • 0:40 - 0:45
    see why this procedure dramatically changed the individual. We know that the
  • 0:45 - 0:49
    prefrontal cortex is important in thinking, and it's imperative for working
  • 0:49 - 0:52
    memory and planned action, and the lower area of the brain is more concerned
  • 0:52 - 0:58
    with emotion. Therefore, some believe the surgery will have the affect of
  • 0:58 - 1:01
    modifying behavior and perhaps disengaging the disruptive thought patterns
  • 1:01 - 1:07
    associated with hallucinations and confused thinking. In reality the procedure
  • 1:07 - 1:11
    produced profound personality changes, often leaving the person listless or
  • 1:11 - 1:17
    appearing absent. In addition there was a likelihood of experiencing seizures.
  • 1:17 - 1:21
    In many cases, people were left in a vegetative state. Now the lobotomy was
  • 1:21 - 1:24
    performed by taking a sharp instrument and placing it near the corner the eye,
  • 1:24 - 1:28
    hammering that in, and then moving the instrument back and forth, thereby,
  • 1:28 - 1:31
    modifying or destroying parts of the brain.
