Electroencephalography (EEG)

The language sciences have benefited extensively from brain imaging technology: Functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) have provided complementary information to experimental data allowing us to better understand the interconnection between brain functioning and behavior. These technologies allow researchers to examine how electrical brain activity is associated with accuracy or response times in a variety of speech and language recognition tasks. This entry introduces the basic concepts of EEG, while illustrating how this methodology captures the timescale of coordinated brain activity.

History

EEG records electrical activity generated by the cortical neurons; contemporary setups generally measure this activity using an array of electrodes placed against the scalp. The first EEG recorded on humans was carried out by Hans Berger in 1924; Berger built upon pioneering physiological ...
