Table 1.
Cortico-cortical evoked potentials. The table illustrates the list of regions showing CCEPs in at least 20% of SPES, the number of contacts sampled in each region and the number of contacts showing above-threshold CCEPs. Numbers in parentheses indicate the number of patients from which results were collected. See electronic supplementary material, table S1 for a list of all sampled regions. ROI, region of interest; sACC, subgenual ACC; pACC, pregenual ACC; MPFC, medial prefrontal cortex; MCC, midcingulate cortex; OFC, orbitofrontal cortex; MFG, middle frontal gyrus; IFG, inferior frontal gyrus; SFG, superior frontal gyrus.
