Localisation of function

Question 1

Function and location of motor cortex

Answer 1

Function:Controls movement and co-ordination of muscles
Location: Frontal lobe

Question 2

Function and location of visual cortex

Answer 2

Function: Controls visual processing and images in visual field
Location: Occupital lobe

Question 3

Function and location of sensory centres

Answer 3

Function: To detect sensation on the skin for reflexes
Location: parietal lobe

Question 4

Function and location of Brocas area

Answer 4

Function: Production of speech
Location: frontal lobe

Question 5

Function and location of wernickes area

Answer 5

Function: Comprehension of speech
Location: Temporal Lobe

Question 6

Supporting evidence for localisation of function: Peterson et al

Answer 6

-Peterson et al conducted brain scans and found that brocas area was active during tasks involving the production of speech and wernickes area was active in tasks involving the comprehension of speech supporting the view language functions are localised and performed in specific brain areas.

Question 7

LOF weakness- Hollistic theory of brain function

Answer 7

Argues that brain functions are not localised but that the entire brain is involved with processing and facilitating behavioural functions-Lashley found that rats did not have a specific localised area to store memories, the entire brain was involved in the storing and processing of memories-brain functions arent locialised, LOF is reductionist as it reduces brain functions to one specific area of the brain and overlooks the entire brain is involved

Question 8

Lateralisation of function

Answer 8

-The idea each hemisphere of the brain performs specialised functions.

Question 9

Contralateral

Answer 9

-Each hemisphere of the brain controls the opposite side of the body-the right hemisphere controls the left side and vice versa

Question 10

Left hemisphere

Answer 10

Responsible for language production and processing, includes brocas and wernickes areas

Question 11

Right hemisphere

Answer 11

Thought to be involved in emotional recognition, pattern and detail recognition and spatial awareness

Question 12

Supporting evidence for LOF: Paul Broca

Answer 12

Case study of a French man with epilepsy who eventually developed an inability to speak, conducted a postmorterm examination and found a lesion on the temporal lobe, suggesting that area is responsible for speech production as when it is damaged, it results in an inhibited ability to produce speech.

Question 13

How does brocas case study support LOF

Answer 13

Because when the area of the brain responsible for speech production is damaged, we lose the ability to speak.

Question 14

What area controls speech production

Answer 14

Brocas area

Question 15

What area controls speech comprehension?

Answer 15

Wernickes area.

Question 16

Who found brain function isn’t localised in rats supporting hollistic brain theory

Answer 16

Lashley

Question 17

Hollistic brain theory: Counter point

Answer 17

-Findings on rats cannot be generalised to humans, humans have more complex brains and more behavioural functions which may need to be localised, things like language etc are localised in humans and not in rats because they cannot speak or understand language-cannot be generalised as humans may have localised functions and theres more evidence to suggest they do-doesn’t weaken the theory.
