Fig. 2

Correlation between serum cortisol levels and voxel values. Scatterplot of serum cortisol levels (Timepoint 1) and voxel values (Timepoint 2) of the region containing the left hippocampus (coordinates -30, -30, -5). The horizontal axis plots serum cortisol levels – averaged value. Zero on the horizontal and vertical axis represent the average value, respectively. The plots on the vertical axis are as follows. Fitted value = voxel value – (average voxel value + error). Plus error = voxel value – averaged voxel value
