Uncertainty quantification for Model V2. Model V2 (red) in comparison with Models D1 (orange) and V1 (blue). The integrated amount of tracer in the a gray matter \(Q_g\) and b white matter \(Q_w\), as defined by (13), over time. The average tracer concentration in a subregion of c gray matter \(q_g\) and d white matter \(q_w\), as defined by (14), over time. The curves show the expected values while vertical bars indicate the 99.73% prediction intervals of the different models
