Re-uptake of potassium by neurons and glial cells

This week on Jurnal Club session Reinoud Maex will present the paper "Computer simulations of neuron-glia interactions mediated by ion flux" , by Somjen, Kager and Wadman(2008) J. Comput. Neurosci. 25, 349-365.

This paper resolves two questions that have bothered me since long:

  • How can (neuronal or glial) potassium channels contribute to the re-uptake of potassium, hence how can the outward flow of potassium become an inward flow?
  • Why is the sodium-potassium pump electrogenic, hence why are three sodium ions exchanged for only two potassium ions?
