The brain region map and the scatter plots of the correlation between the GMV in the left parahippocampus (a) and the right hippocampus/parahippocampus (b) and the Center for Epidemiologic Studies Depression scale scores in individuals with subthreshold depression. The r - values are shown on the color bar. Each circle dot represents the data of one participant. The GMV of the hippocampus/parahippocampus was obtained by defining a sphere centered at the voxel showing the highest statistical differences, with a radius of 6 mm
