Q

What is the somatosensory cortex?

A

The area of the brain that is responsible for detecting sensory events arising

17
Q

Where is the somatosensory cortex located?

A

In both hemispheres - parietal lobe specifically the post central gyrus

18
Q

What are the consequences of damage to the somatosensory cortex?

A

Can cause decrease in sensitivity

19
Q

What is Broca’s area?

A

The are a of the brain that is responsible for speech production

20
Q

Where is Broca’s area located?

A

Only in the left hemisphere - frontal lobe

21
Q

What are the consequences of damage to Broca’s area?

A

Can cause Broca’s aphasia - slow, laborious and lacking in fluency

22
Q

What is Wernicke’s area?

A

The area of the brain that is responsible for language comprehension

23
Q

Whers is Wernicke’s area located?

A

Only in the left hemisphere - temporal lobe

24
Q

What are the consequence of damage to Wernick’s area?

A

Can cause production of nonsense word as part of their normal speech

25
What is the supporting evidence for brain localisation theory?
Tan - Broca 1861 studied a patient that suffered brain damage and could only say the word ‘tan’. He could understand speech and follow instructions. After Tan his brain was examined and they found substantial damage to an area towards the base of the frontal lobe
26
What are the evaluation points for localisation evidence?
+ supported by evidence - Peterson et al 1998 + Highly empirical - Brian scans
27
What are the general evaluation points for brain localisation?
+ Supported by the case study of tan - Broca’s studies - Unrepresentative - only known through tan and phineas gage + Supported evidence - the case study of Phineas Gage - Extrapolation - Lashley 1950
