Localisation Of Function In The Brain

Question 1

What are the three AO3 PEELS to evaluate localisation of function in the brain?

Answer 1

RTS by Broca
Discussion - low pop val
RTC by patient EB

Question 2

P
(RTS by Broca)

Answer 2

RTS by Broca

Question 3

E

Answer 3

his research comes from a case study on a man who could und lang but lost the ability to speak, except for one word “Tan”

Question 4

E

Answer 4

post mortems showed the damage was in one area in LH, now called brocas area

Question 5

L

Answer 5

therefore, this shows the lang production is localised to one specific brain area as theory predicts

Question 6

P
(Discussion - low pop val)

Answer 6

However, Brocas case study can be criticised to have low pop val

Question 7

E

Answer 7

• this is bc it is a unique case study where brain damage may have affected the functionality of the brain
• so it may not be appr to gen findings on LOF to wider pop

Question 8

E

Answer 8

• as some indv may be able to process lang in other areas of the brain
• e.g. some research has found that brocas area is not solely localised in LH but is found in the dominant hemisphere

Question 9

L

Answer 9

therefore suggesting that more research is needed (with more diverse samples) before firm conclusions on the localisation of language areas are possible

Question 10

P
(RTC by patient EB)

Answer 10

In addition, RTC - patient EB

Question 11

E

Answer 11

he suffered from brain damage that resulted in his LH being removed, therefore his lang centres

Question 12

E

Answer 12

• however, EB eventually managed to regain some of his lang ability
• this would not be possible if the lang centres were only localised to LH, as theory suggests

Question 13

L

Answer 13

• this shows lang must be in more areas than just LH
• therefore suggesting a holistic exp of brain functioning is more appropiate than loc of function
