Abstract
With light microscopy, the whole brain was encapsulated by a very dense vascular plexus from which perforating offshoots passed to or from the substance of the brain, while other connections were effected with neighbouring arterial and venous channels. The neopallial part of the cerebral hemisphere was later than all other parts of the brain in receiving vessels perforating its substance. By EM both the extrinsic and intrinsic vessels of the cortex of fetuses up to 10cm crown-rump length were never more mature than capillaries. Within the developing cerebral cortex blind ending solid endothelial sprouts and seamless capillaries were identified.
