Stduying The Brain

Question 1

What are the 4 ways of studying the brain

Answer 1

Post mortem
EEG
FMRI
ERP

Question 2

Post mortem

Answer 2

Brain examined after death
See where damage has occurred and how that could explain previous behaviour

Question 3

FMRI

Answer 3

Repeated scans to create an image of the concentration of oxygen in the blood
Areas of high activity will show corresponding high levels of blood oxygenation and blood flow
Allows sections of the brain that are particularly active during different tasks to be identified

Question 4

EEG

Answer 4

Small sensors attached to the scalp to pick up electrical signals produced when brain cells send signals to each other
Measures amplitude and frequency of electrical activity in brain
Identifies patterns in activity that nay be associated with certain states
Help to identify abnormalities

Question 5

ERP

Answer 5

Measures electrical activity in response to a specific stimulus
In order to identify small specific responses , must take recordings from many presentations and average out the responses to obtain event related potential
