Definition : Encephalographs (EEGs) designed for recording the variations of the electric potential (i.e., data and waveforms) caused by the electrical activity of the brain that include integral microcomputers and/or can interface with other computerized systems. These recorders consist of a main unit that includes a large capacity memory (e.g., a magnetic hard disk, optical disk, electronic drive), signal processors, and appropriate connectors to the output of standard EEGs, other instruments (e.g., EEG monitors, polysomnographs, sleep/awake recorders) or directly to a head box attached to a set of scalp electrodes. The recorder works with one or more dedicated software packages that can perform a variety of computerized studies such as brain mapping, sleep studies, and evoked potential responses according to the user needs. Some recorders may include video EEG capabilities. Computerized EEGs are mostly used to help in the diagnosis of neurological diseases (e.g., epilepsy, sleep disorders) and to assist in localizing and assessing tumors and lesions inside the cranium.
