Abstract

Diameters and densities of arterioles and capillaries were measured in thick alkaline phosphatase-stained sections of human visual cortex from normal young adults. Values were compared between laminae. Capillary diameters ranked:IV > V–VI > II–III > I; capillary densities ranked:IV > II–III > V2V¯I > I. The striking capillary density of lamina IV overlaps the stria Gennarii and, like it, is limited to area 17. The data suggest correlations with similar laminar distributions of some neurotransmitters and of certain common neuropathological lesions.

    However, variations in vascular density alone are not likely the source of the close correspondence between the BOLD responses predicted by the ECoG HFB responses and the measured BOLD responses observed here across subjects. It has been shown that vascular density correlates with cellular density and expected metabolic demand (Adams et al., 2015, Blinder et al., 2013, Bell and Ball 1985, Weber et al., 2008) which could be a neurovascular coupling mechanism that can explain the linear relationship between the measured and ECoG-HFB predicted BOLD. More subjects, however, are needed to investigate the source of response differences between subjects.

    Staining of the endogenous enzyme alkaline phosphatase (AP) has been widely used (reviewed in [32]). Alkaline phosphatase is an enzyme present in the endothelial cells of the BBB, and it has been used to visualize the capillary network of the cerebral cortex and subcortical structures [33–36]. In particular, AP staining labeled numerous blood vessels in all fields of the normal hippocampal formation, and a significant decrease in the density of AP-positive blood vessels has been described in the CA1 of the sclerotic hippocampus [30].
