Localisation

Question 1

Holistic theory

Answer 1

All parts of brain involved in process of thoughts + action

Question 2

Localisation theory

Answer 2

different parts of brain perform different tasks and involved with different parts of body

Question 3

What are the 4 lobes of the brain

Answer 3

-Frontal lobe
-parietal lobe
-Occipital lobe
-temporal lobe

Question 4

What are the 6 areas of the brain and where are they located

Answer 4

-Brocas area (Frontal)
-Motor area (Frontal)
-Somatosensory (Parietal)
-Visual area (Occipital)
-Wernickes area (Temporal)
-Auditory area (Temporal)

Question 5

What does the motor cortex do and in what hemisphere is it located

Answer 5

-voluntary motor movements
-each motor cortex on each hemisphere controls opposite sides of the body
-Present in both hemispheres

Question 6

What the somatosensory cortex do and in what hemisphere is it located

Answer 6

-Detect sensory events
-sensory info from skin produce pain, touch, pressure, temp then localise it
-Recieves info from opposite of body
-Present in both hemispheres

Question 7

What does the visual cortex do and in what hemisphere is located

Answer 7

-receive info from opposite visual field
-contain 7 area, each process different types of visual info e.g movement, colour, shape
-present in both hemispheres

Question 8

What does the auditory cortex do and in what hemisphere is it located

Answer 8

-auditory info primarily decoded before it reaches the brain, receive cochlea to brain stem
-Cortex recognises it and responds in appropriate response
-Present in both hemispheres

Question 9

What does broca’s area do and in what hemisphere is it present

Answer 9

-Speech production
-makes speech fluent
-Left hemisphere

Question 10

What are the 5 AO3 points for localistaion

Answer 10

-Phineas Gage
-Broca and wernicke
-Raine
-Lashley
-Plasticity

Question 10

What does wernicke’s area do and in what hemisphere is it present

Answer 10

-Speech comprehension
-Makes speech meaningful
-Left hemisphere

Question 11

What is the procedure of Phineas Gage

Answer 11

-Case study
-Explosion on railway caused iron pole through frontal lobe

Question 12

What is the findings of Phineas Gage

Answer 12

-everything stayed same but became different person (More aggressive)

Question 13

What is the evaluation point of Phineas Gage

Answer 13

-Supports localisation
X- Weakness is it a case study

Question 14

What is the procedure of broca and wernicke

Answer 14

-post mortem
-studied individuals with speech difficulties
-Broca studied 8 patients who all had damage to frontal lobe

Question 15

What is the findings of broca and wernicke

Answer 15

-Broca found damage to left frontal lobe affected speech production
-Wernicke found damage to left temporal lobe affected speech comprehension

Question 16

What is the evaluation point of broca and wernicke

Answer 16

-support localistaion
X- After death
X- no comparison to healthy brain

Question 17

What is the procedure of Raine

Answer 17

Compare brain scans between murderers who pleaded guilty vs normal PET scans
