-using multiple approaches to address a single question
-ex. Korsakoff’s syndrome
-characterized by severe memory loss
-most commonly seen in alcoholics
-Is Korsakoff’s the result of toxic effects of alcohol on the brain?
It was found that Jimmie G. was a chronic alcoholic.
Once you realize that a chronic alcoholic has developed Korsakoff’s syndrome, the very first
thing you should advise is that the patient stop drinking. Depending on the severity of the
syndrome or the amnesia, if alcohol consumption stops, it is possible for the amnesia to get
Back to Jimmie G. (Korsakoff’s)
-also seen in malnourished persons who had little or no alcohol.
-thiamine deficient rats exhibit memory deficits
-alcohol accelerates development of brain damage in thiamine-deficient rats
-Korsakoff’s is the result of thiamine deficiency, but damage is accelerated by alcohol.
-measure what can be observed
-make inferences about the unobservable
Efferent copies of movements can allow the brain to say whether it is movement within the body
or of a body part that causes something to move or whether it is the object itself that it moving.
From dichotomies to interactions
-is it nature or is it nurture?
-is it ingrained in genetics or is it learned? Generally accepted that it is a combination of
-inherited or learned? Ethology? Behaviorism? Heritability estimates?
-heritability estimates try to estimate how much of the phenomenon can be
attributed to genetics.
-Problems? -is it physiological or psychological
-Cartesian dualism (Descartes) the brain and the body are totally separate.
The man who fell out of bed. Could not identify his own left leg. He believed his left leg was in
fact someone else’s leg and that his was missing. Suffered from Asomatognosia, usually occurs
that the patient cannot identify the left side of their body based on right side brain damage.
-Generally accepted it is nature AND nurture
-how much of each?
