localisation of brain

Question 1

what is localisation of brain function

Answer 1

Localisation theory suggests that certain areas of the brain are responsible for certain processes,
behaviours and activities.

Question 2

4 lobes in the brain

Answer 2

frontal lobe,parietal lobe,temporal lobe,occipital lobe

Question 3

motor cortex

Answer 3

found in the frontal lobe, responsible for voluntary movements

Question 4

brocas area

Answer 4

responsible for language and speech but not understanding

Question 5

auditory cortex

Answer 5

responsible for analysing and processing acoustic information

Question 6

wernicks area

Answer 6

responsible for speech comprehension and located in the temporal lobe

Question 7

somatosensory cortex

Answer 7

receives information form the skin to produce sensations

Question 8

visual area

Answer 8

located in the occipital lobe, which is responsible for visual inofrmation

Question 9

evaluate localisation of brain

Answer 9

+ Supporting evidence for localisation of brain function = Tulving et al demonstrated, using PET scans,
that semantic memories were recalled from the left prefrontal cortex, whilst episodic memories were
recalled from the right prefrontal cortex. This shows that different areas of the brain are responsible
for different functions, as predicted by localisation theory

Question 10

evaluate localisation of brain

Answer 10

+ Supporting Case Studies = Phineas Gage was injured by a blasting rod which intersected the left
side of his face, tearing through his prefrontal cortex. “The damage involved both left and right 2
prefrontal cortices in a pattern that, as confirmed by Gage’s modern counterparts, causes a defect
in rational decision making and the processing of emotion”
