Fig. 1: The hippocampal subregions and significant FC differences between the MDD and HCs.

A The subregions of hippocampus. B–E Significant FC differences between the MDD and HCs for hippocampal subregion, respectively (voxel p < 0.005, cluster p < 0.007, GRF corrected). The color bar indicates the t values from two-sample t test analysis. FC functional connectivity, GRF Gaussian random field, L (R) left (right) hemisphere.
