1. A method for providing an indication of a state of awareness for a patient, comprising:
- acquiring an EEG signal;
filtering the EEG signal to generate a first frequency band of signals;
filtering the EEG signal to generate a second frequency band of signals; and
concurrently displaying the first and second frequency bands of signals in a single display window such that at least a first portion of the first frequency band overlaps, spatially the second frequency band by overlaying one of the first and second frequency band of signals over the other of the first and second frequency band of signals on a same abscissa axis and a same ordinate axis.

Abstract
Providing an indication of a state of awareness for a patient includes acquiring an EEG signal; filtering the EEG signal to generate a first frequency band of signals; and filtering the EEG signal to generate a second frequency band of signals. Providing the indication also includes concurrently displaying the first and second frequency bands of signals in a single display window such that at least a first portion of the first frequency band overlaps, spatially the second frequency band.

12. An apparatus for providing an indication of a state of awareness for a patient, comprising:
-
a receiver configured to acquire an EEG signal; a first filter coupled with the receiver and configured to filter the EEG signal to generate a first frequency band of signals; a second filter coupled with the receiver and configured to filter the EEG signal to generate a second frequency band of signals; and a visual display screen configured to concurrently display the first and second frequency bands of signals in a single display window by overlaying one of the first and second frequency band of signals over the other of the first and second frequency band of signals on a same abscissa axis and a same ordinate axis such that at least a first portion of the first frequency band overlaps, spatially the second frequency band. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
