TABLE 1.

The average diameter (in μm) of intracortical arteries and veins in the modelled vascular unit centred on two intermediate‐sized veins (V3 and V4) and surrounded by four intermediate‐sized arteries (two A3 and two A4).

The average diameter (μm) of the Intracortical vessels (ICAs and ICVs)
Vessel type	V4	V3	V2	V1	A4	A3	A2	A1
Layer I	69	53	32	20	43	33	20	13
Layer II/III	67	51	26		43	32	16
Layer IV	62	41			39	26
Layer V	56				35
Layer VI	44				28

Note: For reference, the ICV diameters of group 1–4 reported in Duvernoy et al. (1981) range from 20 to 65 μm, and the diameter of the corresponding ICAs range from 10 to 40 μm.
