iEEG analysis. (A) Electrode localization. After implantation of electrodes, CT scan was performed to verify electrode location, and was coregistered with pre-operative MRI T1-SPGR images. Data was then evaluated for visual response in posterior temporal electrodes, an example is shown of ERPs response from one patient (#2) (B1). Motor Mu de-synchronization response in the primary motor area is shown using brain power plot maps averaged across all patients (B2). Mean time frequency analysis was used to select the band of gamma frequency (B3). (C) Illustration of the steps included in the iEEG co-activation analysis.
