The specification defines a common representation of all of the data associated with a complete clinical study, including digitized neurophysiological waveforms, textual annotations and interpretive reports. Patterned after existing, related healthcare data interchange standards, it will facilitate data interchange between neurophysiological instruments, computer systems within the neurophysiology laboratory, other information systems in the hospital, and outside healthcare facilities or research laboratories.

The purpose of EEG mapping in epilepsy is to precisely identify and characterize epileptogenic zones of the brain. Such zones may be single or multiple, pointlike or diffuse, and may be near or distant from the recording electrodes. The resulting measured electric fields are used to obtain information which, when analyzed in light of all the complementary clinical information, can frequently help to localize and describe the epileptic foci with more precision.

The system provides graphics for EEG maps and summaries, and is integrated with a 24-h continuous EEG monitoring system. The system can access information from a continually changing database of signals, configurations, and processing parameters to provide up-to-date clinical information. The system provides a foundation for diagnostic work, as well as a platform for clinical neurophysiological research and development

His instru-ment was capable of recording EKG and nerve po-tentials, but its usefulness for EEG was marginal.

This mea- surement takes advantage of the fact that a comb filter will pass the important Fourier harmonics of the signal to provide an estimate of the evoked activity, plus track time-variations in the signal. Results on human subjects demonstrate the effectiveness of the approach.
