If electrical currents on multiple dendrites sum together at the axon hillock, and the current flows across the neuronal membrane to the spike-triggering zone, what is likely to happen?
A)An action potential will be initiated.
B)A sodium-potassium pump will activate.
C)Hyperpolarization.
D)Saltatory conduction.
