Fig. (2) This figure shows the laterality indices for verbal encoding in the Broca (coefficient of determination r²=0.539) and in the MTL ROI (coefficient of determination r2⁼0.131). A significant, inverse correlation (r=-0.802, p=0.017) was seen for activity in the Broca ROI during verbal encoding and subsequent CD change score (decline in verbal memory) for left TLE patients.
