Definition: A measurement of the continuous brain-wave patterns,
or electrical activity of the brain, as recorded with the
placement of small metal discs called electrodes positioned in a
standardized pattern on the scalp. The resulting tracing
reflects the summation of the activity of millions of individual
neurons. The voltage and frequency is interpreted and it is
useful for assessing brain death, seizure activity, and for
determining stages of sleep. Also Known As: Electroencephalogram
The EEG showed that I have seizures while I sleep.
