The top section includes trials within the five broad regions of interest, including trials from dipole 1 (current flowing in) and dipole 2 (current flowing out). Regions include sensorimotor cortex (postcentral/precentral gyrus), IFG (pars opercularis/triangularis), STG (rostral/middle/caudal), supramarginal gyrus, and MTG (rostral/middle/caudal). Columns showing trials with stimulation in other regions are italicized, as these were not included in the present analyses.
The central section includes trials for which stimulation did not induce afterdischarges. Columns showing trials that did induce afterdischarges are italicized, as these were not included in the present analyses.
STG: superior temporal gyrus; MTG: middle temporal gyrus; MFG: middle frontal gyrus
