  • Title: [Inward currents of crab striated muscle fiber measured by the voltage clamp technique with microelectrodes].
    Author: Haudecoeur G, Guilbault P.
    Journal: C R Acad Hebd Seances Acad Sci D; 1975 Jun 02; 280(21):2473-6. PubMed ID: 808286.
    Abstract:
    Membrane currents during depolarisation steps were determined by a method in which three electrodes were inserted near the end of the crab's striated muscular fibre. The value of the reversal potential for the early current appears to be consistent with the calcium equilibrium potential. This early transient inward current is abolished by manganese. The value of about +120mV is consistent with the level of internal free Ca++ ions, as generally tested by different authors.
