A technique that is used to diagnose abnormal electrical activity in the brain.
An instrument that measures the electrical activity of the brain, which is developed in the cerebral cortex as a result of brain functioning. Electrodes are attached to the scalp to record impulses, and these impulses are registered on graph paper as a brain wave pattern. An EEG is used to identify brain damage, tumors, or neurological disorders such as epilepsy: electroencephalogram.
An apparatus which records the electrical impulses in the brain.
The process of recording the electrical impulses in the brain.
The technique for recording the electrical activity from different parts of the brain and converting it into a tracing called an electroencephalogram. The machine that records this activity is known as an encephalograph. The pattern of the EEG reflects the state of the patient’s brain and his level of consciousness in a characteristic manner. Electroencephalography is used to detect and locate structural disease, such as tumors, in the brain; it is also used in the diagnosis and management of epilepsy.
A diagnostic procedure for determining the electrical activity of the brain by the use of equipment which makes recordings (or video displays) from electrodes (electrical contacts) which pick up the electrical impulses. The electrodes are ordinarily placed on the scalp but may, during surgery, be placed on the surface of the brain or in its interior. The record obtained is called an electroencephalogram (EEG).
In the brain there is a regular, rhythmical change of electric potential, due to the rhythmic discharge of energy by nerve cells. These changes can be recorded graphically as electroencephalograms. They are useful in diagnosis: for example, the abnormal electroencephalogram occurring in epilepsy can be used to determine the type of epilepsy, its site of origin in the brain and possibly which treatment is likely to be most effective.
A diagnostic procedure that records, via electrodes attached to various areas of the person’s head, electrical activity generated by brain cells.
Electroencephalography, commonly abbreviated as EEG, is a technique used to record the brain’s electrical activity. The recorded activity is typically visualized on a screen or printed as a continuous line on a strip of paper.
During an EEG procedure, tiny electrodes are adhered to the scalp, which are linked to a device that tracks the brain’s minute electrical impulses. This method can disclose unique wave patterns, aiding in the diagnosis of various forms of epilepsy and pinpointing areas in the brain where unusual electrical activity originates.
The examination and documentation of cerebral wave patterns.
