Answer

Although the following sections frequently cite digital EEG data, these data primarily represent digital analysis of clinical EEG recordings. The referenced data are presumed to be based on an EEG recording that is read by a clinician; presently, recording is done with computerized technology for ease and also for availability for further analysis. Various mathematical transforms are available after the initial clinical interpretation (eg, coherence, Fourier transform, wavelets, and microstates; see Digital EEG). These allow further comparisons with norms and control groups but should be interpreted in conjunction with the primary EEG reading.
