A
EEG
ERP
fMRI
post-mortem examinations
2
Q
EEG stands for
A
electroencephalograms
3
Q
fMRI stands for
A
functional magnetic resonance imaging
4
Q
ERP stands for
A
event-related potential
5
Q
ERP stands for
A
event-related potential
6
Q
fMRI definition / procedure
A
- detects change in blood flow/ oxygenation
- active brain areas consumes more oxygen - brain activity
- patients sit still under a scanner
-produces activation maps (3D images)
7
Q
EEG definition / procedure
A
- measures electrical activity in the brain
- electrodes fixed at the scalp
- used as a diagnostic tool for clinicians - brainwaves - arrhythmic patterns can be indicative of neurological abnormalities
8
Q
ERP definition / procedure
A
- almost same as EEG
- can test and identify sensory / cognitive / motor events
- statistical averaging techniques
- repeat of EEGs - and average out the most common brainwave pattern
9
Q
Post-mortem examination definition / procedure
A
- invasive analysis of brain after death
- surgical procedure
- areas of damage analysed
