Abbreviations ERNI Error Relative to No Intervention value; WCC Weighted Correlation Coefficient. The Targeting Index means the proportions of the regions of the ipsilesional activation area given stimulation. The miss-hit Index represents the proportions of the non-activated area that was stimulated
