Last notes (I believe) from my Abnormal psychology .........(note book 3)

Social network can work positive or negative eg. Meeting a couple. Woman is dying from lung cancer and smoking, with husband’s support. Suicide encouragement - negative. (Since this lecture assistant suicide is legal). Biological Approaches - The question as to why Stressors tend to effect different people in different ways. Salier saw general things, but all types of conditions are different in arousal patterns for different states - A clear response to anger and fear can be easily missed. Lacy’s work in the 60’s - very specific responses. Immune System: Skin >wood sliver breaks off inside (skin) > fragments break off>antigen. Immune system sends out cells. Looks at shape and does two things - 1. encapsulates the antigen. 2. Secretes enzymes which degrade the invaders. Anti bodies produced to kill (scavenge) the antigens. Now bacterial/virus as opposed to wound. 1. First recognizes antigen, not part of the body (as do with all proteins) - then as before. Then stores a picture of this (so to speak) and next time antibodies shape specific for this antigen. Stress inactivates the immune system, one of biological approaches. If people are stressed - activity in immune system are reduced. Cancer - when cells starts producing antibodies, if immune system is repressed, people don’t have the benefit of this system. Another class of disease - Auto immune disease eg. polo. Recognition mechanism is a bit faulty. Immune system has forgotten it is part of own body, therefore immune system destroys healthy body tissue - paradoxically x cells as well by stress. Regarding head injury. Some people incorrectly say that to have brain damage one must be non conscience. Empirically - cut corpus callosum in epilepsy - provides learning experience- if fire for a minute and repeats….nerve fibre goes to the other side of corpus callosum - after a few months bilateral response because other side learned - cut corpus callosum - prevent secondary. He poked the brain while patient was awake to figure out how it worked. Eg. If extensive brain damage and no loss of consciousness. Diagram : Brain shake by bang of head - if no shock wave - does not pass out. When test patient - attention, memory, planning, emotional instability. Studies more recent - possible brain damage without unconsciousness. Soplosky -depicts that when people/animals are stressed, a tremendous increase in excitatory amino acids and stress hormones called Gluco Corticoids cells of the hippocampus (memory control centre) and the connections it makes with the frontal lobes. Hippocampus states is an important store for short term to long term but not stored there. Directs other cells to convert to short term to long term. Frontal lobes contribute to memory as follows; Hat, cow, pencil etc….. Easier to remember four classes of items such as clothes, tools, spices; animals. ^ not recall } recognition , no internal ^ cues to help retrieve search. Frontal lobe does this. Gluc Corticoids seem to gravitate to the two parts of the brain and do their damage. What has this got to do with functioning? Neurophysiological malfunction in schizophrenic drugs or not. (I have completed book 3 of notes of Abnormal psychology. The rest of my notes are a review for a test which I won’t place here. I am sure it would be boring for you. Next week I shall continue with the Theology notes and then decide what is next from my notes for you. Perhaps a course I took in Masculinity and Man. That was a Social Science course which was the easies course I ever took. How would you like me to share that with you? Til then. Have a wonderful weekend.
