An electroencephalogram is a test that is conducted to measure and record the electrical activity of brain. Special sensors like electrodes are attached to head and hook to a computer that records brains electrical activity. Electroencephalogram Helps in detecting certain neurological disorders such as epilepsy.
Sleep disturbances were studied using Electroencephalogram by comparing certain sleep encephalogram patterns in a group of patients with anorexia nervosa. The recording can be performed non-invasively, directly on the brain cortex or within the brain (depth EEG), Electroencephalography is a medical imaging technique that reads scalp electrical activity generated by brain structures.
The electroencephalogram (EEG) is measuring electrical activity of an alternating type recorded from the scalp surface using metal electrodes and conductive media.
