    Area of Science:

    • Neuroscience
    • Medical Technology
    • Signal Processing

    Background:

    • Epileptic seizure processing involves automatic recognition and detailed analysis.
    • Electroencephalograms (EEGs) during seizures lack clear morphology, complicating automatic recognition.
    • Widespread monitoring makes detailed seizure pattern analysis valuable.

    Purpose of the Study:

    • To review methods for analyzing seizure patterns, focusing on inter-channel time differences.
    • To illustrate how these methods can track seizure propagation and identify driving brain structures.

    Main Methods:

    • Computation of millisecond-level time differences between EEG channels.
    • Analysis of seizure propagation patterns and evolution across brain structures.
    • Review and illustration of established analysis techniques.
