|
A supporting point of localization in the brain? |
fMRI scans objective scientific evidence, one study found Broca's area active during reading task |
fMRI and Broca |
|
|
How has neurosurgery supported this idea? |
Use of it to remove/destroy parts of brain to control troublesome or undesirable behavior |
|
|
|
How have 44 OCD patients proven this? |
Underwent a cingulotomy, after 32 weeks 33% had reduced symptoms, 14% had partial improvements |
|
|
|
Are there gender differences? |
Research shown women have larger Broca's and Wernicke's areas then men meaning a greater use of language |
|
|
|
What is a strong challenge to the idea of localization in the brain? |
Research into brain plasticity |
|
|
|
How is this so? |
People who damaged specific cognitive functions are sometimes able to functionally recover these functions |
|
|
|
How is that? |
The brain roerganises itself, undamaged neurons takes the role of the damaged |
|
|
|
What does this suggest? |
That the brain operates on a holistic rather than localised basis |
|
|
|
What has research shown about learning and other cognitive processes? |
Don't appear to be linked to specific areas, bit distributed in a more holistic manner |
|
|
|
What study has shown this? |
Removed between 10-50% of the cortex in rats learning a route through a maze, no area was found to be more important than any other in this research |
|
|
|
The conclusion? |
Learning involved every part of cortex rather than localized areas so suggests some processes require all parts of the brain |
