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.

The patch-clamp technique was used to investigate the activity of single ion channels in neuropile glial (NG) cells in the central nervous system (CNS) of the medicinal leech, Hirudo rnediciaulis. We found evidence for two distinct C1-channels that could be distinguished by their basic electrical pr
We investigated the effects of ATP (adenosine 5Π-triphosphate) and derivatives on leech neuropile glial cells, focusing on exposed glial cells. ATP dosedependently depolarized or hyperpolarized neuropile glial cells in situ as well as exposed neuropile glial cells. These potential shifts varied amon
