Localisation Of Function In The Brain

Question 1

What is the localisation of function

Answer 1

Theory that different areas of the brain are responsible for specific behaviours processes or activities

Question 2

What is the main part of the brain called

Answer 2

The cerebrum

Question 3

What is lateralisation

Answer 3

Some of our functions are controlled dominated by one hemisphere

Question 4

What does the right hemisphere control

Answer 4

Activity on the left hand side of the body is controlled

Question 5

What does the left hemisphere control

Answer 5

Activity on the right hand side of the body

Question 6

What is the cerebral cortex

Answer 6

Outer layer of both hemispheres

Question 7

What are the 4 lobes of the brain

Answer 7

Frontal lobe
Parietal lobe
Occipital lobe
Temporary lobe

Question 8

What is a lobe

Answer 8

Part of an organ that is separate in some way from the rest of the

Question 9

Where is the motor area located

Answer 9

At the back of the frontal lobe

Question 10

What does the motor area control what happens if it gets damaged

Answer 10

Voluntary movement in the opposite side of the body
Damage to this areas of the brain may result in a loss of control in fine movement

Question 11

Where is the somatosensory located

Answer 11

At the front of both parietal lobe which is separated from motor area by a valley called central sulcus

Question 12

What does the somatosensory area control

Answer 12

Sensory information from the skin is represented. The amount of somatosensory area devoted to a particular body part denotes its sensitivity for instance receptor for our face and hands occupy over half of the somatosensory area

Question 13

Where is the visual area located

Answer 13

In the occipital lobe at the back of the brain

Question 14

what does the visual area do

Answer 14

Each eye sends information from the right visual field to the left visual cortex and from the left visual field to the right visual cortex

Question 15

what happens when to the visual area when the left hemisphere is damaged

Answer 15

can produce blindness in part of the right visual field of the both eye

Question 16

where is the auditory area

Answer 16

temporal lobe

Question 17

what does the auditory area do

Answer 17

analyses speech based information

Question 18

what when there is damage to the auditory area

Answer 18

partial hearing loss

Question 19

where is the Brocas area

Answer 19

frontal lobe in the left hemisphere responsible for speech

Question 20

where is the Wernickes area

Answer 20

temporal lobe encircling the auditory cortex in left hemisphere responsible for language comprehension

Question 21

in most people where is language restricted

Answer 21

left side of the brain

Question 22

what did Paul broca identify

Answer 22

identified a small area in the left frontal lobe responsible for speech production

Question 23

what happens to damage of the Broca area

Answer 23

causes Broca aphasia characterized by speech that is slow and lack in fluency and preposition and conjunctions

Question 24

What is Wernicke aphasia

Answer 24

people who had no problem producing language but difficulty understanding it such that the speech that they produced was meaningless

Question 25

what is a STRENGTH

Answer 25

-Damage to area of the brain has been linked to mental disorders
-Neurosurgery is a last resort treatment for treating some mental disorders
-Darin Doughtery reported on 44 people with OCD who had undergone a cingulotomy
-after 32 weeks about 30% had met criteria for successful response to surgery and 14% for partial response
The success of these procedures suggests that behaviours associated with serious mental disorders may be localised

Question 26

what is a LIMITATION

Answer 26

Language may not be localised to Brocas area andd Wernickes area
-Anthony Dick and Pascale Trembley only 2% of modern researcher think that language in the brain is completely controlled by Broca’s and Wernicke’s areas
-FMRIs mean that shows language function is distributed holistically in the brain
-Language streams have been identified the across cortex

Question 27

what is the frontal area

Answer 27

located behinfd the forehead vital for functions including voluntary movement and impulsive control

Question 28

what is the parietal area

Answer 28

located to the frontal lobe anterior to the occipital and superior process the sense of tpouch

Question 29

what is the temporal area of the

Answer 29

play a role in managing emotions processing information from your senses, storing and retrieving memories and understanding

Question 30

what is the occipital area of the

Answer 30

seat of the most brain visual cortex allowing you not only to see and process information
