Topology - UCSB Physics
... The topology of the central nervous system has been, and remains today a topic of considerable study. It is known that for humans, the central nervous system starts in the embryo as a plate, eventually deforming into a tube, one end of which thickens to become the brain (the remainder being the spin ...
