Figure 3. Association between Dorsolateral Prefrontal Cortex Activation and Duration of Euthymia.

Left: The sagittal image (Montreal Neurological Institute plane x= 12mm) displays the right dorsolateral prefrontal cortex region (BA9) in which response during the fearful vs. neutral face condition was significantly associated with duration of the current euthymic period in the participants with remitted major depressive disorder (n=19), at P<0.001. The color bar shows the T values. The maxima was at coordinates x=12, y= 46, z= 34; Ke= 75 voxels. Right: The graph demonstrates the positive correlation between the months of the current euthymic period in the participants with remitted major depressive disorder (n=19) and the percent of blood oxygen level dependent signal change extracted from the peak of the right dorsolateral prefrontal region shown in the image to the left, r= 0.69, r²= 0.47.
