title: Off-line montage reformatting.
abstract: A method is described for off-line reformatting of recorded EEG data to any desired montage, gains, filter settings and paper speed. Thirty-two channels, including every scalp electrode, are recorded in a common referential montage and multiplexed onto videocassettes . Playback onto an EEG machine faithfully reproduces the original signals, so that any final montage may be specified at the EEG selector panel, with common mode rejection of the recording reference. The technique has proven especially useful in prolonged seizure monitoring and in the clarification of events which occur only rarely in the course of routine EEGs.
