Web400 Hz. . . For each frequency of stimulation, indicate whether the period between stimulation is longer or shorter than the length of an action potential. Length of action potential in pyramidal neuron is about 15-20 milliseconds (msec). 25 Hz. Web8 aug. 2014 · An action potential is a brief (only a few milliseconds) reversal of the membrane potential ( Vm ). At rest, the Vm of a neuron is around −70 mV (closer to the equilibrium potential for potassium, VK ), but during an action potential, Vm transiently approaches +50 mV (closer to the equilibrium potential for sodium, VNa ). flangia plasson
