A method of displaying signals containing a spatial and a temporal aspect,
where multiple signals are received by multiple sensors. The received
signals are decomposed into separate signal components within one or more
distinct frequency bands. Signal components are isolated within each
frequency band based on differences between the signal components within
the same frequency band, and the signal components are displayed. The
signal components may be analyzed to determine a time course of activity
and a location of the associated source. Representations of the source
may also be generated and displayed to aid in monitoring the signals.
