New functions for glia in the brain.
T or twenty years ago, glial cells were considered minor players in the nervous system, even though they outnumber neurons 10-fold. Glia were thought to function as passive support cells, bringing nutrients to and removing wastes from the neurons, whereas the latter carried out the critical nervous system functions of information processing, plasticity, learning, and memory. Recent studies, rev...

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولNew roles for glia.
Recent findings suggest that glial cells, though lacking the excitability usually associated with most neurons, may be more actively involved in brain function than has been previously thought. Collectively, these findings indicate that glial cells can sense, and potentially respond to, a large array of neuronal signals. Because glial cells are intimately associated with most neurons, neurobiol...

15 صفحه اولThe role of glia in neurological disease
Glial cells form a network in the central nervous system to support neurons and interact with them. The glia consist essentially of astrocytes that help with the nutrition of neurons and react in some cases of injury, oligodendrocytes that produce myelin, and microglia that are derived from the haemopoietic system and are concerned with the immunological defense of the nervous system. Experimen...
