Table A2.

Frequentist multiple regression parameters. The parameter values for the models with the highest adjusted r². The model using the exact coordinates reported in previous studies is presented at the top; the model using peak correlations within an ROI is presented at the bottom. The peak coordinate from the mask ROI condition [21 −58 66] is included in both models. Inclusion of GABA+/Cr ratio resulted in a lower r² for both model types and is thus not presented in the table.
