  channel availability
(1984) we estimated the distortion of the time course of recovery of Vmax from that of sodium channel availability in the presence of drugs.
      
The underlying mechanism was found to be a significant increase in the channel availability, defined as the ratio of current-containing sweeps to the total number of sweeps.
      
This effect of NECA on mean current was due to a reduction of the channel availability and a slight decrease in the open probability.
      
The increase in mean current was brought about by an increase in the channel availability, defined as the ratio of sweeps containing Ca2+ channel activity to the total number of depolarizations.
