Figure 5: Ictal electrocorticography. (a) Subclinical seizure pattern. Focal seizure onset (red arrow) in PCR, ipsilateral propagation (orange arrow) to MCR. (b) Clinical seizure pattern associated with clonic jerks of the left hind limb. Focal seizure onset (red arrow) and end registered in PCR. Note the absence of ictal electromyographic activity in the left temporal muscle. (c) Detail of clinical seizure pattern. Note the close correlation between repetitive ictal bursts in MCR (red arrows) and contralateral facial twitching (orange circles) as evidenced by temporal electromyography (TML). MCR, right motor cortex; MCL, left motor cortex; PCR, right parietal cortex; TML, left temporal muscle; red bars, seizure end.
