Y1 - 2021 N1 - T2 - Principles of Neural Science, 6e AB - A VAST ARRAY OF NEURONS AND GLIAL CELLS is produced during development of the vertebrate nervous system. Different types of neurons develop in discrete anatomical positions, acquire varied morphological forms, and establish connections with specific populations of target cells. Their diversity is far greater than that of cells in any other organ of the body. The retina, for example, has dozens of types of interneurons, and the spinal cord has more than a hundred types of motor neurons. At present, the true number of neuronal types in the mammalian central nervous system remains unknown, but it is surely more than a thousand. The number of glial types is even less clear; unexpected heterogeneity is being discovered in what was thought, until recently, to be rather homogeneous classes of astrocytes and oligodendrocytes.
