    Accurate localization of the epileptogenic zone is crucial for successful surgery in drug-resistant focal epilepsy.

  • 2

    Stereo-EEG is the most precise method for identifying the epileptogenic zone, revealing significant heterogeneity in ictal patterns.

  • 3

    The harmonic pattern identified in ictal EEG recordings may provide insights into the nonlinear dynamics of ictal networks.

  • 4

    Quantitative EEG analysis methods, such as the epileptogenicity index, have been developed to enhance the localization of the epileptogenic zone.

  • 5

    The study utilized bispectral analysis to confirm the nonlinear nature of the harmonic pattern in focal epilepsy patients.
