Spikes on ripples are better interictal biomarkers of epilepsy than spikes or ripples

L Fabbri, MAG Matarrese, S Jahromi… - Brain …, 2025 - academic.oup.com
Spikes are the most established interictal epilepsy biomarkers. Yet, they suffer from low
specificity since they are partially concordant with the epileptogenic zone and often found in …

Overlap of spike and ripple propagation onset predicts surgical outcome in epilepsy

S Jahromi, MAG Matarrese, L Fabbri… - Annals of Clinical …, 2024 - Wiley Online Library
Objective Interictal biomarkers are critical for identifying the epileptogenic focus. However,
spikes and ripples lack specificity while fast ripples lack sensitivity. These biomarkers …

Classifying High-Frequency Oscillations by Morphologic Contrast to Background, With Surgical Outcome Correlates

K Qing, E Von Stein, L Yamada, A Fogarty… - Journal of Clinical …, 2022 - journals.lww.com
Purpose: Ictal high-frequency oscillations (HFOs) are a reliable indicator of a seizure onset
