Document Summary
Frontal lobe frontal lobotomies > prefrontal area aka anterior are of the frontal lobe. Gall > phrenology > anterior portion intelligence [sherlock holmes] Jacobsan > 1930 > tested this theory in monkeys: trained them in intelligence and then performed frontal lobotomies, monkeys had a loss in delayed response abilities [and tool abilities] Feeman and watts > brought moniz to na: performed 3 500 frontal lobotomies personally, 40 000 performed in the us, 18% > developed seizures w/i a 10year period, 1950 > declined due to drug treatments for depression/schizo/affect. Not just frontal lobotomies can be from a accidents [young people] Temporal lobe/hippocampus short-term memory > through consolidation > long-term memory. Hippocampus > develops late, needs lots of blood/oxygen: most commonly damaged area > scar tissues > seizures/epilepsy. Will not remember previously doing the task but will show improvement: they can gain memory they just cannot verbally tell you about it.
