    Area of Science:

    • Neuroscience
    • Biomedical Engineering
    • Signal Processing

    Background:

    • Electroencephalogram (EEG) data acquisition typically involves fixed recording parameters.
    • Reformatting EEG data post-acquisition is often limited, hindering detailed analysis.
    • The need for flexible EEG data manipulation for complex neurological conditions is growing.

    Observation:

    • A new method records 32-channel EEG data in a common referential montage.
    • Data is multiplexed onto videocassettes for off-line reformatting.
    • Playback on an EEG machine reproduces original signals faithfully.

    Findings:

    • The described method allows off-line reformatting of recorded EEG data to any desired montage, gains, filter settings, and paper speed.
    • Any final montage can be specified post-recording with common mode rejection.
