Figure 2

Residuals in 2D and 3D Hotelling filter. The residual for Raclopride plotted as a function of time for striatum and cerebellum ROIs. The residual represents the difference between filtered and original data, and is thus a measure of the bias at each time frame. A) 3D Hotelling filter (PC1-4), which displays a large time-varying error. B) 2D Hotelling filter (PC1-4), where the striatal uptake displays a considerably lower error.
