Can someone give me feedback on this evaluation please!

Evaluate the fact that the brain is localisation [10 marks].

I wrote this answer in PEEL points (obviously I would write it properly in the exam). I wrote 4 paragraphs, even though my teacher told me that 3 would be enough. This is equal to just over 1.5 pages when written.

P - There is brain scan evidence to support localisation of function in the brain.
E - Peterson et al used brain scans to demonstrate that Broca's area was active during a reading task whereas Wernicke's area was active during a listening task.
E - This suggests that Broca's and Wernicke's area have different functions and that separate areas of the brain aren't active at all times.
L - This therefore supports brain localisation - that different areas of the brain are responsible for different activities, processes and behaviours.

P - There's also case studies to support brain localisation.
E - For example, Phineas Gage received serious trauma to his brain, severely damaging his frontal lobe, causing his personality to change.
E - This suggests that the function of the frontal lobe is to regulate mood.
L - Furthermore, Gage's case study demonstrates that even when certain areas of the brain are damages, other areas continue to function properly, thus supporting brain localisation.

P - However, such case studies lack population validity as they're based on the experience of one person, therefore they aren't representative of the population as a whole.
E - Studies have found that women have much larger Broca's and Wernicke's areas than men.
E - This suggests that there are individual differences in the structure of the brain, and therefore there may also be differences in the function of the brain.
L - As a result, Gage's case study findings cannot be generalised to the wider population.

P - A final limitation of brain localisation is that it's been suggested that communication is much more important than localisation.
E - Wernicke suggested that although different areas of the brain are specialised in different functions, they're all interdependent in the sense that in order to work, they must all interact with each other.
E - This suggests that if one brain area was damaged, it would cause other areas of the brain to not function properly.
L - Therefore, the brain isn't truly localised.
