localisation of function Flashcards
what are the 4 lobes of the brain?
(farmer people own tractors)
frontal, pariental, occipital, temporal
what are the 6 areas of the brain?
(many soggy vaginas are willy buckets)
motor area
somatosensory area
visual area
auditory area
wernickes area
brocas area
outline the somatosensory area?
front of pariental lobe,
where sensory info from skin is represented
numbers/ tingling if damaged
outline the motor area?
back of frontal lobe
controls involuntary movement on opposite side of body
loss of control over movements if damaged.
outline the visual area?
in occipital lobe
info from visual field from opposite cortex
blindness in opp eye if damaged
outline the auditory area?
in temporal lobes
analyzes speech based info
hearing loss if damaged
outline the brocas area?
left frontal lobe
speech production
brocas aphasia If damaged, speech lacks fluency, slow
outline the wernicke’s area?
left temporal lobe
language comprehension
wernicke’s aphasia if damaged, nonsense words.
which case study supports localisation of function?
Phineas Gage
what occured in this case study?
survived metsl rod entering skull, recovered well with working memory
intellectually and socially impaired
damage to left frontal lobe, behaviour
ao3 brain scan evidence? localisation of function
strength
Peterson et al (1988) scanned brains to demonstrate wernickes area active in listening tasks and brocas in reading
ao3 neurological evidence? +cp localisation of function
strength
lobotomies used to treat aggressive behaviour and mental health conditions like ocd.
destroy/ removed connections in frontal lobe which controlled self control
success rate 63%
cp- not 100% effective and traumatic for person
ao3 holistic evidence? +cp localisation of function
limitation
Lashley (1950’s) removed 10-15% of rats cortex’s, learnt to do a maze
no parts localised and whole brain works together
cp- unethical and cant generalise human brain to rats.
