## Abstract The structural and functional similarities between Mรผller cells and oligodendrocytes prompted the present study of the electrophysiological properties of Mรผller (glia) cells obtained from the retinae of control and myelin mutant __taiep__ rats during the postnatal developmental period (

Double-barrelled microelectrodes, sensitive to quaternary ammonium ions, were used for simultaneous measurements of the intracellular free concentrations of choline ([Ch],) or tetramethylammonium ([TMAIJ as well as membrane potential (Em) in neuropile glial cells of the leech, Hirudo medicinalis.

## Abstract Retinal glial Mรผller cells are characterized by dominant K^+^ conductances. The cells may undergo changes of their membrane currents during ontogeny and gliosis as described in rabbit and man. Although the rat retina is often used in physiological experiments, the electrophysiology of r
Intracellular electrical recordings in onion (Allium cepa L.) guard cells show that they maintain a membrane potential difference (MPD), inside negative. The MPD of intact cells averaged -72\_+ 29 mV (n = 45); MPD of cells partially digested with a cellulolytic enzyme, -39 +\_ 7 mV (n = 65). Evidenc
