encephalograms
Cranial electrical tracings
Encephalograms are graphic records of brain activity, typically produced by measuring electrical signals through electrodes placed on the scalp.
The term usually refers to electroencephalograms (EEGs), used to diagnose seizures, sleep disorders, and other neurological conditions: The encephalograms showed abnormal activity in the temporal lobe.
