localisation of function in the brain

Question 1

frontal lobe

Answer 1

motor area which controls voluntary movement in the opposite side of the body
and expressive language

Question 2

temporal lobe

Answer 2

location of auditory ability such as the analysis of speech based information

Question 3

occipital lobe

Answer 3

location for vision, nerve fibres from the inner half of the retina of each eye travel to the opposite sides of the brain

Question 4

parietal lobe

Answer 4

somatosensory area responds to heat, cold, touch, and pain and our sense of body movement

amount of somatosensory area devoted to a particular body part denotes its sensitivity

Question 5

cerebral cortex of both hemispheres is divided into 4 lobes:

Answer 5

frontal
parietal
occipital
temporal

Question 6

motor area

Answer 6

back of forntal lobe
controls voluntary movement

damage = loss of control over fine movements

Question 7

somatosensory area

Answer 7

front of parietal lobes
processes sensory info about the skin (touch)

Question 8

visual area

Answer 8

in the occipital lobe

each eye sends info form the right vidual field to the left visual cortex

Question 9

auditory area

Answer 9

in the temporal lobe
analyses speech based info
damage = partial hearing loss

Question 10

where is wernicke’s area

Answer 10

left temporal lobe

Question 11

effects of damage: temporal lobe

Answer 11

left temporal lobe results in linguistic deficits - known as Wernicke’s aphasia

Question 12

effects of damage: frontal lobe

Answer 12

result in loss of control over fine movements

Question 13

damage to occipital lobe

Answer 13

damage to left hemisphere can produce a loss of vision to the right side

Question 14

where is Broca’s area

Answer 14

left frontal lobe

Question 15

localisation

Answer 15

certain areas of the brain have specific functions

Question 16

localisation case study PEE

Answer 16

P = research to support
E = Phineas Gage, during an accident, had an iron pole go through his left cheek and exit his brain and skull. he survived by his temperament had changed from being kind and reserved to boisterous and rude
E = this supports localisation because it shows the left frontal love is responsible for regulating temperament

Question 17

lateralisation

Answer 17

some physical and psychological functions are controlled by a particular hemisphere

left side of body control right hemisphere

Question 18

lateralisation: left hemisphere

Answer 18

language

Question 19

lateralisation: right hemisphere

Answer 19

recognising faces

Question 20

cerebral cortex

Answer 20

the outer layer of both hemispheres and covers the inner parts of the brain
3mm thick
what separates su from animals - human’s is more developed

Question 21

wernicke’s area

Answer 21

language understanding

Question 22

wernicke’s aphasia

Answer 22

Patients are able to produce speech that resembles fluent language but actually is meaningless

Question 23

broca’s area

Answer 23

speech production

muscle movements for speech

Question 24

Broca’s aphasia

Answer 24

deficit in the ability to produce language, reading and writing
language comprehension generally preserved

Question 25

Broca's evidence

Answer 25

tan, who could only say the word tan conducted a postmortem and found an impaired ability to produce language due to damage to Broca's area

Question 26

localisation ao3 - brain. scan evidence to support

Answer 26

Petersen et al used brain scans to show activity in Wernicke's area during a listening task and Broca's area during a reading task there are a number of objective methods for measuring activity in the brain providing sound, scientific evidence of localisation

Question 27

counter point for localisation ao3

Answer 27

however, Lashley removed areas of the cortex in rats learning the route through a maze. learning required all of the cortex rather than being confined to one particular area this suggest that higher cognitive processes are not localised but distributed in a more holistic way in the brain

Question 28

localisation - model has been questioned ao3

Answer 28

Dick and Tremblay found that very few researchers still believe language is only in Broca's and wernicke's area advanced techniques such as FMRI have identified regions in the right hemisphere this suggest that rather than being confined to a couple of key areas, language may be organised more holistically in the brain

Question 29

localisation - evidence is limited ao3

Answer 29

as unique cases if neurological damage, such as Phineas Gage its difficult to make generalisations based on a single individual as conclusions may depend in the subjective interpretation of the researcher suggests that some evidence supporting localisation may lack validity, oversimplifying brain processed and undermining the theory
