In the absence of such detailed information, regions with high diversity or many unique species are often assumed to be hotbeds of species origination, but a new theory demonstrates that such places could instead result from the immigration of species. This theory, outlined in an a......ors Frank Kirchhoff and Fritjof Helmchen provide a detailed description of microglia behavior in the normal brain and in response to cerebral hemorrhage. In the normal brain, the researchers found that fine processes of so called "resting" microglial cells are not at rest at all.
