Concentration dependence of two components of NA-activated current. A: NA (50 mM) activated a transient current (a) followed by a sustained tonic current (b). Dashed line indicates the holding current during the sustained component. B and C: concentration dependence of the NA-activated transient (B) and sustained tonic (C) currents. Numbers on graphs indicate the quantity of neurons recorded for each concentration.
