Fig. 4.
Contact pairs of interest. A ECoG contacts (black dots), and finger tapping BOLD increases (red). B Spectral differences for contralateral and ipsilateral (to the icEEG contacts) finger tapping periods. COIα, COIβ and COIγ are highlighted with white circles (left, centre and right column, respectively). C Pre-surgical electrical stimulation results. Contacts showing peaks of apparent artefactual origins (harmonic high-amplitude peaks (prominent residual gradient artefacts), or a 50 Hz (electrical component) high-amplitude peak) were not analysed, and are displayed as a dotted cross. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
