Abstract
In his modest little textbook on Animal Physiology (2nd Edition, W.H. Freeman and Co., New York, $32.95) Roger Eckert (1983) devotes 12.2 cm of text to the potassium-buffering function of neuroglia (see glial cells). Indeed, the selective permeability of glial cells to K+ and the role of glial cells in K+ homeostasis in the neuronal microenvironment has been reasonably well established during the past 20 years (Kuffler, 1967; Coles, 1985). More recently, evidence has accumulated indicating that glial cells may express voltage sensitive channels, albeit at low density, to other ions, including Na, CI“, and Ca (for review see Ransom and Carlini, 1986). However, such channels appear to open at membrane potentials far removed from those naturally occurring in glial cells; there is no evidence they participate in glial function.
