Understanding Schizophrenia 1. Autopsies show that schizophrenics have 6 times the number of receptor sites for the neurotransmitter dopamine . Therefore, it was thought that dopamine antagonists, like thorazine, or haldol, would help the disorder. There is a progressive reduction in cerebral tissue, which is then replaced by cerebrospinal fluid. PET scans show reduced metabolic activity in schizophrenics.
Activity is seen in the thalamus during hallucinations.
Schizophrenia is associated with flu epidemics in a country. Sexual Disorders First we need to think of a continuum of acceptable sexual behavior across cultures. At one extreme, it is very repressive, such as the island of Iris Beag. In this culture, they can t deal with seeing nudity, even when they have sex they keep as many clothes on as possible. Men find sex to be stressful and want to get it done with as soon as possible.
