Multichannel electroencephalography (EEG)

Methods for recording brain activity

Electroencephalography  (EEG) is the recording of electrical activity along the scalp. EEG measures voltage fluctuations resulting from ionic current flows within the neurons of the brain.Electroencephalography is a safe and non-invasive method, which has a very good time resolution, but a poor spatial resolution. EEG is widely used in diagnostics and research, as well as in real-time applications (e.g. BCIs).
