Maps of electrode pairs and stroke lesions in this study. (a) Electrode pairs used for the computation of the F7F8-PSI, F7T5-PSI, and F8T6-PSI. They are located in the motor language-related regions. (b) Electrode pairs (F3F4, F3P3, and F4P4) spatially adjacent to those in (a) (F7F8, F7T5, and F8T6) used for evaluation of the effect of artifacts. They are not located in the motor language-related regions. (c) A map of the ischemic stroke lesion distribution in 31 patients. The colors indicate the number of patients with lesions. PSI phase synchrony index.
