Book 19913rd editioncovered, of particular interest are subjects that oftentimes received superficial coverage in texts, including separate, detailed chapters on oligodendrocyte and astrocyte development, and developmental mechanisms that relate to the process of aging. Multi-authored texts are often tricky to assemble

Even if neuroglial cells did not exist Virchow would have had to intent them as a requirement for his theory — as a bold conjecture thrown out for refutation. But techniques were inadequate to either corroborate or refute that conjecture. the me

For the past century these problems—origin, migration, and fate—have been the manun conceptual platforms from which research programs on

One of the major assumptions of the late 19th century was that animal cells lack a cell membrane. The cell surface was believed to be a transition

The most important advance in our understanding of the historical development of the neuron theory is that it did not originate in the 1880s and 1890s as a single theory but was constructed over a much longer period, starting in the

The history of ideas about the modes of termination of peripheral nerve fibers parallels that of ideas about endings of nerve fibers in the central nervous system (CNS). Until the 1860s it was generally believed that the peripheral nerves end by anastomosin
