Fig. 3.

Prior and posterior distributions for GM volume correlations. Prior = red, posterior = blue. Prior distributions are based on the correlation coefficient and number of participants in the original studies. Distributions are plotted for all coordinates reported in Table 1, except for the mask ROI peak for which the original correlation was unknown. Left: Results for the exact coordinates reported in previous publications. Right: Analyses for the peaks within a spherical ROI centred on the coordinates reported in previous publications. Grey dots indicate the probability density at rho = 0 (i.e., the likelihood of no correlation) for each curve.
