localisation of function

Question 1

what is it

Answer 1

functions like movement speech and language performed in distinct brain regions
opposite view is brain act’s holistically

Question 3

contralateral

Answer 3

each hemisphere of the brain (right and left) control the opposite side of the body including both motor and sensory pathways

Question 4

hemispheric lateralisation

Answer 4

each hemisphere is specialised to perform different functions eg: language centres in left hemisphere and visospatial in right

Question 5

motor cortex

Answer 5

voluntary muscle motor movements across the body
at the back of the frontal lobe
damage: loss of muscle function or if severe paralysis on opposite body sidd

Question 6

somatosensory cortex

Answer 6

receiving sense impressions from around the body

front of the partial lobe

damage: loss of sensation in opposite side

Question 7

broca’s area

Answer 7

located in left frontal lobe only
responsible for speech production
damage: motor aphasia or difficult producing fluent speech

Question 8

wernickes area

Answer 8

located in left frontal lobe only
speech comprehension
damage: sensory aphesia/ difficult understanding speech

Question 9

auditory cortex

Answer 9

receives and processes sound info from ears
located in both hemispheres

Question 10

visual cortex

Answer 10

occipital lobe
visual processing each hemisphere
receives info from opposite visual field

Question 11

positives

Answer 11

clive wearing (amnesia) language and memory recollection are localised and in dif areas

modern brain scan like fmri support older research on language centres- activation in regions when they perform tasks

Question 12

negative

Answer 12

case studies aren’t scientific

some functions like consciousness appear to not be localised at all so the theory is dependent on the function
