PS101 Lecture Notes - Lecture 6: Thalamus, Head Injury, Lobotomy
Document Summary
A large amount of people develop some form of dementia by the time they are 90. However it has also been found that some of these traits can be hereditary, especially alzheimer"s. Monozygotic rate is 50% while dizygotic is 30% When looking in the mind of an alzheimer"s patient, you find plaque as well as tangled brain pieces, along with a shrunken cortex. Estrogen and vitamin e have been found to help avoid alzheimer"s. People have shown a lot of great recovery from brain damage such as strokes. Gage had a nail shoot through his pre frontal cortex, back to work, but seemed like a different person. (pre frontal lobotomy) he managed to perform it perfectly. Psychotherapy is dealing with an intact brain. (also called dbs- deep brain stimulation) You do psychotherapy by going through the temporal cortex, the eyes, or a needle strait from the top with a heated end (thalamus)
