Voxel-wise correlation analyses between apathy scores (AES-C) and FA in aMCI patients (n = 29). The following are depicted (red-yellow): left IFOF/UF (z = 5); genu CC (z = 19, y = 25); body CC (z = 33, y = 9); ACR bilateral (z = 25, y = 25); SCR bilateral (z = 38); ATR bilateral (z = 19, z = 28, y = 25); right SLF (z = 33 and z = 38). For better visualization, the results were thickened using the “tbss-fill” command. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
