Localisation Of Function In The Brain

Question 1

What is localisation of function

Answer 1

Specific functions (physical and psychological) have specific locations in the brain

Question 2

What are the 4 lobes that make up the brain

Answer 2

Occipital, temporal, parietal, frontal

Question 3

What are the 6 specialised areas of the brain

Answer 3

Motor, somatosensory, visual, auditory, Broca’s, Wernicke’s

Question 4

What is a case study which shows support for localisation of the brain

Answer 4

Phineas Gage

Question 5

What is the role of the motor cortex and where is it found

Answer 5

Controls voluntary movement in the opposite side of the body. Found in the back of the frontal lobe

Question 6

What is the role of the somatosensory cortex and where is it found

Answer 6

Processes sensory information related to touch, pressure, pain and temperature which it then localises to specific body regions. Found in the parietal lobe

Question 7

What is the role of the visual cortex and where is it found

Answer 7

Each eye sends information from the right visual field to the left visual cortex and the left visual field to the right visual cortex. Found in the occipital lobe

Question 8

What is the role of the auditory cortex and where is it found

Answer 8

Analyses speech based information. Found in temporal lobe

Question 9

What is the role of Broca’s and Wernicke’s area

Answer 9

Broca’s area- speech production. Found in frontal lobe, left hemisphere
Wernicke’s area- speech comprehension. Found in temporal lobe, left hemisphere

Question 10

How does Phineas Gage show support for localisation of function in the brain

Answer 10

The change in his personality and temperament following the accident suggests that part of the brain that is responsible for regulating temperament is in the frontal lobe
