Fig. 2.

Joint independent component analysis (jICA) of brain tissue composition and shape deformation. Panel (a) shows the mixing coefficients for the depressed and control subjects wherein the central red mark is the median, the edges of the blue box are the 25th and 75th percentiles, and the whiskers show the extreme values of the coefficients. Panels (b), (c), and (d) show the joint source map of the most significant component for (b) GM, (c) WM, and (d) deformation field. The green dots indicate the boundaries of the region of the interest which was created by dilating a mask around the hippocampus.
