11. Electroencephalography is the measurement of brain activity through the surface of the scalp.12. This may include electroencephalography ( EEG ) or magneto-encephalography ( MEG ). 13. Continuous electroencephalography monitoring is recommended in symptomatic patients. 14. The use of Electroencephalography ( EEG ) can exclude temporal status epilepticus from consideration. 15. Electroencephalography ( EEG ) is a procedure that records electrical activity along the scalp.16. Electroencephalography or EEG shows somewhat more persistent alpha waves of slightly lower frequency than usual.17. For instance, before the introduction of electroencephalography , epilepsy was frequently confused with hysteria. 18. This usually involves a dental examination, and possibly electroencephalography if a seizure disorder is suspected. 19. Polysomnography may involve electroencephalography , electromyography, electrocardiography, air flow monitoring and audio video recording. 20. Delta waves, like all brain waves, can be detected by electroencephalography ( EEG ).
