Frontal Lobe Lecture 10
- the posterior section deals with primary motor strip, getting info out
-more anterior deals with higher order function (association cor tex) such as appropr iate
behaviours
Frontal lobotomies:
- deals with prefrontal area ( anterior portion of frontal lobe)
-developed through GALL phrenology, he said that anterior frontal lobe deals with
intellectual functioning
- using this Jacobson did test on monkeys on memory and intelligence test then removed
anterior por tion and repor ted: - loss in delay response capabilities ( if they saw a solution
to a problem and were asked to solve it r ight after, they were able to. However if there was
a delay between seeing and action they could not)
-therefore he thought there was a problem with immediate/short term memory, but
noticed that when left in the dark or on a sedative t hey were able to solve problem
suggesting that problem was not in memor y but in distractibility (emotionality)
-also saw problems in alternation (WGTA)
-had a irate monkey that was use for test , then after test was manageable and different
-Dr. Munioz noticed this and began seeing if this could be done on humans with mental
disorders( severe)
-results (based on 20 ppl) : 7 showed recovery, 7 showed improvement
- Freeman and Watz brought in to NA until revealed it caused massive scar tissue and
18% of patients developed siezures during 10 yr span, now drugs are used as substiute
Symptoms:
-did not effect intelligence/ IQ
-problems in changing in appropriate behaviour in context ( WCST cards alternating;
recall the monkeys and the blue and red cup)
-dissociation between verbal and motor behaiour (left light touch with your r ight hand,
they w ill do this and eventually begin doing left light left hand but still say the
instructions properly
-problems inhibiting inappropr iate behaviour ie) game rules * they know the rules but are
impulsive
- personality traits: -live in immediate present, do not plan for future
-lack initiative, unreliable (can hold job)
- commonly talks in puns jokes
-limited attention span(distractible)
-impaired judgement and insight
