- Ways of studying the brain: A03
- fMRI
- Non-invasive
- Doesn't rely on the use of radiation
- Other scanning techniques do (e.g. PET)
- A safer alternative to the patient
- Poor temporal resolution
- 5-second lag between initial neural activity and image
- May not truly represent moment-to-moment brain activity
- Non-invasive
- Post-mortem
- Improve medical knowledge
- Allows close-up analysis of a brain or brain area
- Helps generate hypotheses for further study
- Issues of consent before death
- Patients may be unable to provide informed consent e.g. patient HM
- Can cause problems between psychologists and family of the deceased
- Improve medical knowledge
- ERPs
- Specific measurement of neural processes
- More specific than raw EEG data
- More accurate diagnosis than EEG
- Background noise and extraneous material must be completely eliminated
- Time consuming
- Difficult to achieve
- Specific measurement of neural processes
- EEG
- High temporal resolution
- Detects brain activity at a resolution of a millisecond
- More representative of brain activity than fMRIs
- Difficult to know exact source of neural activity
- Can't distinguish between the activity of adjacent neurons
- Lower accuracy in diagnosos
- High temporal resolution
- fMRI
