- Brain Investigation: Evaluation
- EEG's
- Safe and painless way of measuring brain activity
- Often used as a diagnostic tool when looking at epilepsy and sleeping disorders
- PET Scans
- Expensive
- Results aren't easy to interpret. E.G. The brain is always active so not easy to ascertain which area is specific to which activity
- Neurosurgery
- Allows experimenter high degree of precision over what area of the brain is removed
- Damage is not reversible
- Cannot generalise animal research to humans
- MRI Scans
- Show clear images of the brain and can "slice" the brain to get a view of certain areas
- Hard to analyse as is specific to each person
- Post-Mortem Examinations
- Can see what effect certain diseases have physically on the brain.
- Cannot compare what the brain was iike before and after.
- Limited sample of the population
- EEG's
- Hard to analyse as is specific to each person
