Intracellular Magnesium

  • First-time comparative measurements of intracellular [Mg2+] in different types of muscle in frog (Xenopus laevis) and crayfish (Procambarus clarki and Pacifastacus leniusculus) using ion-selective microelectrodes (Günzel & Galler, 1991) 
  • Regulation of intracellular [Mg2+] in 3 types of neurons (multifunctional Retzius neurons, mechano­sensoric P-(pressure-) neurons, non-classified Leydig-(50-) neurons) and in Neuropil glia cells of the leech (Hirudo medicinalis
  • Mg2+ regulation in neurons of the CA1 region of rat hippocampus
