Abstract Triple-barrelled, ion-sensitive microelectrodes were used to investigate the regulation of intracellular Mg 2+ in Retzius neurones of the medicinal leech ( Hirudo medicinalis ). There is strong evidence that Mg 2+ extrusion from Mg 2+ -loaded Retzius neurones is mediated by an amiloride-sensitive Na + Mg 2+ - antiport , possibly working at a stoichiometry of 1: 1. In contrast, Mg 2+ influx pathways are more complex. Mg 2+ influx could be partially inhibited by the Ca 2+ channel… CONTINUE READING
