Answer 3

speech
thought
learning

Question 4

Answer 4

hearing and memory

Question 5

what does the parietal lobe take care of

Answer 5

processing sensory information

Question 6

what does the occipital lobe take care of

Answer 6

visual processing

Question 7

what does the diencephalon contain

Answer 7

the thalamus and hypothalamus

Question 8

what dows the thalamus and hypothalamus do

Answer 8

relay nerve impulses from the body to the brain

Question 9

what is the cerebellum involved in

Answer 9

the control of balance and co-ordination

Question 10

what does the brain stem regulate

Answer 10

regulates autonomic function (breathing)
information is passed through here connecting brain and spinal cord

Question 11

where is the motor cortex located in the brain

Answer 11

the frontal lobe

Question 12

what does the motor cortex control

Answer 12

its responsible for the control of voluntary motor movements

Question 13

true or false do both hemispheres have a motor cortex

Answer 13

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

Question 14

what would damage of the motor cortex lead to

Answer 14

impaired movement ability

Question 15

where is the somatosensory cortex located

Answer 15

parietal love

Question 16

what is the somatosensory cortex responsible for

Answer 16

the detection of sensory events arising in different parts of the body

Question 17

TRUE or FALSE do both hemispheres have a somatosensory cortex

Answer 17

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

Question 18

what would damage of the somatosensory cortex lead to

Answer 18

impaired sense percception

Question 19

where is brocas lobe located

Answer 19

in the left hemispheres frontal lobe

Question 20

TRUE or FALSE is there a brocas area in both hemispheres

Answer 20

FALSE
only the left

Question 21

what is brocas area responsible for

Answer 21

processing language and production of language

Question 22

what would damage to brocas area lead to

Answer 22

difficulties in producing speech

Question 23

who discovered brocas area

Answer 23

paul broca due to his research into his patient tan

Question 24

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

Answer 24

-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

Question 25

where is wernickes area located

Answer 25

the left temporal lobe

Question 26

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

Answer 26

FALSE
its found in the left temporal lobe only

Question 27

what is Wernicke’s area responsible for

Answer 27

the sensory input of language

Question 28

what would damage of wernickes area lead to

Answer 28

failure to understand language

Question 29

where is the visual centre located

Answer 29

within the occipital lobe

Question 30

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

Answer 30

yes

Question 31

what is the visual centre responsible for

Answer 31

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

Question 32

where is the auditory centres located

Answer 32

within the temporal lobes

Question 33

damage to the visual centre leads to

Answer 33

damaged visual perception

Question 34

TRUE or FALSE is there temporal lobes on both hemispheres

Answer 34

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

Question 35

where is the auditory cortex found

Answer 35

temporal lobe in both hemispheres

Question 36

what is the auditory cortex is concerned with

Answer 36

hearing

Question 37

does the auditory cortex have contralateral function

Answer 37

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

Question 38

how does information travel to the auditory cortex

Answer 38

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

Question 39

what is a strength of localisation of function

Answer 39

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

Question 40

what is a weakness of localisation of function

Answer 40

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
