Harmonic patterns embedded in ictal EEG signals in focal epilepsy: new insight into the epileptogenic zone

2023-12-22

Abstract excerpt

<h4>ABSTRACT</h4> <h4>Objective</h4> Localization of the epileptogenic zone (EZ) requires further refinement. We identified a unique ictal spectral structure, the ‘harmonic pattern’ (H pattern), which potentially serves as a novel biomarker for localizing the EZ. This study aimed to analyze the clinical significance of the H pattern and to explore its underlying waveform features. <h4>Methods</h4> Seventy patients...
