title: [Ca2+ dynamics in glial cells].
abstract: Because glial cells have been characterized by electrophysiological studies as being silent and inactive, neuroscientists have overlooked the roles of these cells in the dynamic function of the central nervous system. Recent measurements of intracellular Ca2+ concentration, however, revealed the dynamic and active features of the glial cells. Some populations of these cells gave rise to increase in intracellular Ca2+ concentration by stimulation with neurotransmitters such as glutamate, acetylcholine, serotonin, noradrenaline and histamine through the activation of specific neurotransmitter receptors distributed on the glial cells. Although the roles of the increased intracellular Ca2+ concentration in glial cells have not been elucidated, these properties suggested the functional participation of glial cells in synaptic modulation and plasticity.
