localistaion

Question 1

localisation of function

Answer 1

-diff parts of brain perform diff functions
-when area of brain is responsible for particular function we say it is localised to that part of brain

Question 1

hemispheric lateralisation

Answer 1

-the L+R side of brain perform diff functions
-connected by corpus callosum which is a bundle of axons that enables communication between the hemispheres

Question 2

motor cortex

Answer 2

-controls r body movements by sending signals to muscles in body
-organised contralaterally=MC in LH controls R side of body
-in frontal lobe

Question 3

visual cortex

Answer 3

-occutipal lobe
-recieves+processes visual info like colour, shape or movement
-organised contralaterally
-nerve impulses go to the retina then to VC via optic nerves

Question 4

auditory cortex

Answer 4

-temporal lobe
-auditory info
-not organised contralaterally
-cochelea detects sound then to brainstem for processing then AC

Question 5

somatosensory cortex

Answer 5

-processes r feeling of touch, pain, pressure+temp
-organised contralaterally
-in parietal lobe

Question 6

language centres

Answer 6

-in left hemipshere
-wernicke area: speech perception/understand language. recieves sound impulses+processes its meaning then to brocas
-brocas area: sounds r assembled so enables us to produce language.
-then to MC+speech muscles

Question 7

aphasia

Answer 7

-when ppl lose ability to produce or understand language
-happens if damage to areas
-brocas aphasia: inability to produce language
-wernickes aphasia: inability to undertsand language

Question 8

ao3

broca study

Answer 8

-brocas pateint ‘tan’ struggled to produce language
-performed post mortem exams on him + showed damage to now called brocas area

Question 9

limitations

Answer 9

-oversimplified
-ignores importance of communication between regions
-ignores indivual differences in brain organsiation
