Ways Of Investigating The Brain

Question 1

Outline- FMRI

Answer 1

Scan where it detects brain activity by detecting radio waves in the brain while a patient does a task. Detects where oxygen is in the brain.

Question 2

Outline- EEG

Answer 2

Scan that Detects tiny electrical impulses produced by the brain and measures wave patterns

Question 3

Outline- ERPs

Answer 3

-measuring brain activity when given an event that will stimulate the brain

Question 4

Outline- post Mortem

Answer 4

Examining the brain after death

Question 5

Evaluation- s+w of FMRI

Answer 5

Strength- it’s risk free, no radiation

Weakness- it’s expensive

Question 6

Evaluation- s+w of EEG

Answer 6

Strength- Improved diagnosis of epilepsy

Weakness- doesn’t pinpoint exact sources of neural activity

Question 7

Evaluation- s+w of ERPs

Answer 7

Strength- very specific measurements of neural processes

Weakness- lack of standardisation in ERP methodology between different studies

Question 8

Evaluation- s+w of post Mortoms

Answer 8

Strength- was vital for original foundations of the understanding of the brain. Broca and wernicke relied on it
Weakness- can’t define the causation of these things.
