EEG
EEG is one of the oldest methods for assessing the relationship between brain and behaviour, and provides a direct real-time measure of neural activity. EEG is recorded using electrodes placed at specific locations across the scalp; hence it is relatively inexpensive and easy to apply. Until now, equipment restrictions have limited research to the laboratory, but recent advances in mobile EEG equipment have opened up a wealth of new research opportunities. EEG provides limited spatial resolution about the origins of neural activity, but it has exceedingly high temporal resolution – making it ideal for tracking the rapid execution of sensory, cognitive and motor processes in real-world contexts.
