New 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...
متن کاملGABA and neuroactive steroid interactions in glia: new roles for old players?
In recent years it has becoming clear that glial cells of the central and peripheral nervous system play a crucial role from the earliest stages of development throughout adult life. Glial cells are important for neuronal plasticity, axonal conduction and synaptic transmission. In this respect, glial cells are able to produce, uptake and metabolize many factors that are essential for neuronal p...
متن کاملEmerging roles for enteric glia in gastrointestinal disorders.
Enteric glia are important components of the enteric nervous system (ENS) and also form an extensive network in the mucosa of the gastrointestinal (GI) tract. Initially regarded as passive support cells, it is now clear that they are actively involved as cellular integrators in the control of motility and epithelial barrier function. Enteric glia form a cellular and molecular bridge between ent...
متن کاملNew 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...
متن کاملa new approach to credibility premium for zero-inflated poisson models for panel data
هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
