Computational domain. a The computational domain representing the brain parenchyma including the cerebellum. The interior lateral ventricles are marked (light blue) in the central region of the domain. Two smaller regions of interest \(S_g\) and \(S_w\), in the gray and white matter respectively, are marked in red (\(S_w\)) and yellow (\(S_g\)). b Representation of the gray (darker gray) and white matter (lighter gray) in the computational domain (axial slice)
