Fig. 2: Scatterplots depicting the nature of correlational relationships between striatal normalized T2*-weighted (nT2*w) signal and Go-NoGo performance-based indices across patients, as reported in Table 2.

For nT2*w signal, higher values indicate lower tissue iron concentration; for task indices, higher values indicate better performance. Sex differences in nT2*w are simultaneously illustrated through individual points for female (red, filled) and male (blue, hollow) participants. Scatterplots depict nT2*w correlational relationships with performance-based indices of A emotion discrimination; B emotion regulation; and C cognitive control.
