Noncolumnar patterns of blood flow with the interconnected vascular network.
The standard model of cortical columns has network has tightly linked vascular network. It graph was carefully studied and theoretically analyzed. The results concluded that the microvascular that forms the subsurface, has formed a topology by the interconnected loops. And it is consistent with the boundary and the position of columns.
Furthermore, it was calculated that the blood flow patterns in the cortical column network are not related to the column's location. Instead, to limit lateral perfusion venues were penetrated that drained the sourced blood effectively by penetrating the arterioles.
Therefore, this analysis helps in understanding the effect of penetration strokes of vessels and its functional imaging on the viability of the brain.
