Fig. 9.

Individual structural trajectories using a linear model. Three random subjects (1 NO, 1 sMCI, 1 pMCI) were chosen and we demonstrate local trajectories in three example voxels from the anterior lateral temporal lobe GM (upper row), temporal lobe WM (middle row), and lateral ventricle (bottom row). The observed data is shown in blue, the individual predicted trajectory g(t, θ_i⁽¹⁾) is shown in green including the ± 2 standard deviation of its posterior uncertainty (gray area) and the contour plot of the uncertainty pdf outside the ± 2 std area. The uncertainty is mainly driven by the parametrization around the center of mass of age r_t in the whole group.
