Electroencephalography (EEG)

About this technology

Electroencephalography (EEG) is a technique to measure the electrical activity of the brain. EEG is a clinically used for the diagnosis of many neurological disorders. In the field of neurological research EEG has become popular because the technique is relatively cheap, easy to use, painless and non-invasive. EEG is measured by placing electrodes on the scalp of a subject or patient. Each electrode picks up the very small electrical discharges at the surface of the brain. The amplitude of the EEG signals is in the range of +/- 100 uV and is recorded using a very sensitive amplifier.
In the FOCOM project TMSi amplifier technology is used for the EEG experiments.
