Highly consistent temporal lobe interictal spike networks revealed from foramen ovale electrodes

•Interictal spike network is highly reproducible across time and frequency bands in temporal lobe patients with foramen ovale electrodes.•Interictal spike networks are both bilateral and unilateral, where they are closely related to seizure onset zones and structural lesions.•A small fraction of mesial temporal Spikes are associated with cortical spikes but without a clear pattern of propagation.
