Main pageElectroencephalography


Electroencephalography (EEG) - a non-invasive diagnostic method used to study brain bioelectrical activity using EEG. The test is an appropriate location on the skin surface of the skull electrodes, which record changes in electrical potential on the surface of the skin, derived from the activity of neurons in the cerebral cortex and the right to enhance their entry form - electroencephalogram. If you place the electrodes directly to the cerebral cortex (eg during surgery) study called elektrokortykografii (ECOG). The first Polish EEG was recorded by Adolf Beck in Jagiellonian University, which his work published in 1890, the first EEG performed on a man, Hans Berger, a psychiatrist at Jena. The standard study, 19 electrodes are placed in the system 10-20.
