Figure 1

The iEEG and sEEG electrode locations and single channel accuracies (SCAs) for the six subjects (A–F). For each subject, the iEEG SCA topographies are plotted on generic brain models on the top with the electrode locations indicated by the circles. The black circles represent the electrodes that were used for the BCI recordings and modeling, whereas the white electrodes were only used for the clinical recordings and not represented in the models. The sEEG SCA topographies are on the bottom with the black dots representing the fixed 32-channel electrode positions according to the International 10–20 system [27]. Note that the iEEG figure for Subject C represents hippocampal depth electrodes through an axial cross-section, which are not illustrated as a contour plot. The SCAs were determined by using the ERP amplitude features from a single channel to derive the respective channel’s classifier based on [13].
