In the telencephalon—the new brain—the floral similarity increases. Its nerve fibers divide indefinitely, like the branches of a tree. This process is called, appropriately, arborization. In the proliferation of those twiggy fibers, tiny deposits of neuromelanin are cast off like seeds. The neuromelanin seeds apparently are the major organizing molecules in the brain. They link up with glial cells to regulate the firing of nerve cells. When we think, when we originate creative ideas, a literal blossoming is taking place. A brain entertaining insights is physically similar, say, to a jasmine
