STICK ELECTRODES ON SCALP INSTEAD.
- Raw data from each electrode.
-EEG records voltage changes produced by synaptic activity by placing electrodes on scalp.
POSITIVES: High temporal resolution (fast)
- Can reveal differences in processing speed for different stimuli.
NEGATIVES: Poor spatial resolution .
- not due to amount of electrodes which fit on head.
- Waves from different spatial locations flow across the scalp and interact (add up+cancel out).
-Makes it difficult to interpret and localise signal sources in EEG.
