Summary
Intracerebral vessels of the parietal lobe of the rhesus monkey have been examined by electron microscopy with special reference to the relationship between the leptomeninges and the cerebral cortex. A “perivascular reticular sheath”, in apparent communication with the subarachnoid space surrounds intracerebral arterioles. Myo-endothelial junctions occur in intracerebral arterioles, but no nerve fibres are found in association with such vessels. This indicates that the tone of these vessels may be regulated by chemical mechanisms, possibly mediated through the myo-endothelial junctions.
