Cortical microvascular blood flow velocity mapping by combining dynamic light scattering optical coherence tomography and two-photon microscopy.

A decreasing trend of capillary flow velocity was observed at the first four branching orders following precapillary arterioles (from 4.3 to 1.1 mm / s ), whereas mean flow velocity was similar across the capillaries of the first four branching orders counted from the postcapillary venules ( ∼ 0.8 mm / s ).
