Abstract

In the past few years digital technology has brought EEG and evoked potentials into emergency rooms, intensive care units and operating rooms with a variety of automatic data trending. Networking of these systems makes access to clinical neurophysiologists nearly immediate. Digital EEG has made montage reformatting and quantitation of parameters readily available. Increased spatial and temporal resolution is available with routine EEG, and combined topographic and frequency mapping of a given potential, spike or seizure focus is possible. In the future, these and other features such as dipole mapping and cognitive EP analysis will be available on a routine basis.
