Tension development in voltage-clamped barnacle muscle fibers occurs with depolarizing pulses so small as not to activate the potassium and calcium conductance systems. Peak tension and the tension time integral appear to be graded by both amplitu...

The ionic mechanism underlying the time-dependent alteration in the action potential configuration by noradrenaline (NA) was studied using vas deferens muscle vlotage-clmaped according to the double sucrose gap method. Early exposure to NA enhance...

Barnacle muscle fibers subjected to constant current stimulation produce a variety of types of oscillatory behavior when the internal medium contains the Ca++ chelator EGTA. Oscillations are abolished if Ca++ is removed from the external medium, o...

The effects of phalloidin (10(-14)-10(-6) M) were tested on voltage-clamped isolated frog muscle fibres. The toxin reversibly blocked the potassium current similarly in both detubulated and intact fibres. Neither the reversal potential nor the act...
