From: Phase-amplitude coupling between infraslow and high-frequency activities well discriminates between the preictal and interictal states

Figure 7

Contacts related to SOZ and nSOZ (P5-S3). (a) Illustration of implanted electrodes and the brain are displayed. The numbers correspond to the contacts’ number. This illustration was drawn by Hiroaki Hashimoto using Procreate (Savage Interactive Pty Ltd, Hobart, Australia, https://procreate.art/ipad). (b) The high-intensity lesion in the right occipital lobe is shown on the fluid-attenuated inversion recovery MRI (red wedge arrows). This lesion is indicated by the arrow in (a). (c) The SOZ contacts, which include A31, A32, A36, and A37, placed on the lesion initially show infraslow activity immediately after SO (0 s), followed by low-voltage fast waves. At that time, nSOZ contacts of A40, A41, A54, and A55 show no epileptic changes. The number of SOZ and nSOZ contacts are the same.
