Q

TRUE or FALSE do both hemispheres have a somatosensory cortex

A

TRUE
as one side of the brain controls the opposite part of the body

18
Q

what would damage of the somatosensory cortex lead to

A

impaired sense percception

19
Q

where is brocas lobe located

A

in the left hemispheres frontal lobe

20
Q

TRUE or FALSE is there a brocas area in both hemispheres

A

FALSE
only the left

21
Q

what is brocas area responsible for

A

processing language and production of language

22
Q

what would damage to brocas area lead to

A

difficulties in producing speech

23
Q

who discovered brocas area

A

paul broca due to his research into his patient tan

24
Q

what did Broca’s research into tan allow him to conclude

A

-tan could only produce the sound ‘tan’ but could understand language when spoken to him, brocas studied patients with similiar damage in the right hemisphere and noticed they didnt have the same difficulty
this le dhim to believe it was the language centre of the brain and only in the left hemisphere

25
Q

where is wernickes area located

A

the left temporal lobe

26
Q

TRUE OR FALSEis wernickes area found in both sides of the hemisphere

A

FALSE
its found in the left temporal lobe only

27
Q

what is Wernicke’s area responsible for

A

the sensory input of language

28
Q

what would damage of wernickes area lead to

A

failure to understand language

29
Q

where is the visual centre located

A

within the occipital lobe

30
Q

TRUE OR FALSE is the visual centre found on both sides of the hemispheres

A

yes

31
Q

what is the visual centre responsible for

A

the opposite visual fields visual cortex collects information about the color, shape, movement

32
Q

where is the auditory centres located

A

within the temporal lobes

33
Q

damage to the visual centre leads to

A

damaged visual perception

34
Q

TRUE or FALSE is there temporal lobes on both hemispheres

A

true
as the alternative side of the brain processes info for the opposite ear

35
Q

where is the auditory cortex found

A

temporal lobe in both hemispheres

36
Q

what is the auditory cortex is concerned with

A

hearing

37
Q

does the auditory cortex have contralateral function

A

YES
the alternative side of the brain processes the information for the opposite ear

38
Q

how does information travel to the auditory cortex

A

the sound is slowly decoded through different stages on its path to the auditory cortex for
duration, intensity and pitch of the sound at the brainstem and thalamus
before completing its journey to the auditory cortex

39
Q

what is a strength of localisation of function

A

P: There is support from case studies
E: unique cases of neurological damage support the localisation theory such as nicolas cage
E: cage survived a pole going through his brain resulting in his personality being affected to become angry quickly
L: The change in Gages temperament following the accident suggests frontal lobe is responsible for regulating mood

40
Q

what is a weakness of localisation of function

A

P - one weakness of LOF is through Lashley equipotentiality theory

E - this suggests that the basic motor sensory functions are localised but higher mental functions are not. Whilst also claiming intact areas of the cortex could take over responsibility for specific cognitive functions following brain injury.

E - this is a weakness as it suggests functions are not localised too just one region

L - therefore the research shows that LOF lacks validity as other regions can take over specific functions following a brain injury
