Fig. 1. (a) Realistic slice of an adult head model showing the complex boundaries between the main tissue components: scalp, skull, CSF layer, gray matter and white matter.
Fig. 4. Sketch of the spatial evolution of fluorescent markers inside a five-layered head model associated to three tested indicators to noninvasively delineate the lateral boundaries.
Fig. 5. Plots of Δ 〈t〉 acquired at two source–detector separations sets x d ¼ 5-3 mm, x d ¼ 8–5 mm, against the change of the reduced scattering coef fi cient (0.1–1 mm − 1 ) of the CSF layer located in a five-layered head model.
