  1. Phantom Limbs and Lobotomies!! Psychology Riverside High School Mrs. Cavell

  2. Learning Targets: Discuss and analyze the occurrence of phantom limb phenomenon Explain the use of lobotomies as a treatment for mental illness in the early to mid-twentieth century in the US

  3. Think about it… You are driving on a remote road during a blizzard. Your car hits an icy patch and you skid into an embankment. You are not seriously injured but your right leg is trapped. After 24 hours pass you realize that no one is going to find you. Would you…

  4. JUST A THOUGHT!! • Cut off your own leg with a pocket knife?

  5. Phantom Limb – A Case Study • In 1993, Donald Wyman was in the forest driving a bulldozer. • A giant oak tree suddenly fell and pinned him to the ground. • He was all alone and no one could hear his shouts for help. • Donald knew what he had to do. • He took out his 3 inch pocket knife and cut off his leg, just below the knee.

  6. More about Donald • He was bleeding badly, but was able to drag himself to his truck and drive a mile and a half down the road to get help. • His limb was too badly damaged to be reattached. (they recovered the part of his leg he sawed off) • Donald now has an artificial limb that is fitted to the stump of his leg.

  7. His Recovery • His recovery went well, though he does have a problem. • “The toughest part since the accident is dealing with phantom pain. It feels like somebody’s holding an electrical shock to your foot that’s not there. It makes you jump around.” • We are now going to discuss the strange phenomenon of the phantom limb.

  8. Do have any ideas on why phantom limb pain occurs? • Yes…I am ready to share my answer. • Sort of…Not really sure if I want to take a guess. • No Ideas!! 15

  9. Phantom Limbs • Doctors have been puzzled by the phantom limb since they were first reported in 1866. • Phantom limb – Feeling sensations or movements coming from a limb that has been amputated. • These sensations are felt as if the limb were still present.

  10. Does this happen frequently? • The vast majority of individuals claim to feel sensations or intense pain coming from their removed limb. • They often refer to it as “pins and needles” • They insist that it is “real” pain, not memories of previous pain. • Some individuals claim that their phantom limb was still present and that it was stuck in certain positions. (straight out from their bodies) • Some felt that they had to be very careful not to hit their phantom limb when going through doorways!

  11. Answers: #1: • Sensations come from cut nerves in the stump. • Early research thought that when nerves were cut near the spinal cord, phantom limb should have been prevented. • The sensations still remained though. • This early answer has been rejected.

  12. Answer #2: • Sensations come from the spinal cord. • If sensations from phantom limbs do not come from the stump, perhaps they originate in the spinal cord. • Well…Even individuals whose spinal cords have been severed above the stump report phantom limb sensations. • A severed spinal cord prevents sensations. • This theory doesn’t work either.

  13. Answer #3: • Sensations come from the brain itself. • Researchers have enough data now to indicate that the origin of phantom limb sensations must be the brain itself. • They are still puzzled however, how the brain generates sensations from phantom limbs.

  14. Answer #4: • Sensations come from a body image stored in the brain. • This theory states that we are all programmed with a system of sensations that show us where are body parts are. • Based on sensations from body parts, the brain pieces together a complete body image. • Having this “body image”, the brain can generate sensations coming from any body part, even if that part is a phantom limb.

  15. Have you ever experienced phantom cell vibration? • Yes…All the time! • Occasionally. • What’s a cell phone 15

  16. Between a Rock and a Hard Place: The Story of Aron Ralston • Aron was forced • to cut off his own • arm when he became • trapped while rock climbing. • Let’s hear his story!

  17. Do you plan on trick or treating this year? • Candy…must have candy! • I prefer to steal my younger siblings candy. • Halloween is for halloweenies!

  18. Lobotomies…You don’t need that part of your brain?! • LOBOTOMY: The removal of some of the pre-frontal lobe (no real scientific precision) • WHY? To help alleviate all sorts of mental illness symptoms. (Depression to Schizophrenia) • WHO? Dr. Walter Freeman • HOW: Using an ice-pick like instrument (leucotome), inserting them into the eye-socket and breaching the bone and removing portions of the brain.
