B) The distance between the presynaptic cell and postsynaptic cell determines the frequency of action potentials.
C) The degree of sustained depolarization at the axon hillock determines the frequency of action potentials.
D) The number of postsynaptic cells that a presynaptic cell is communicating with determines the frequency of action potentials.
E) The length of the presynaptic cell axon determines the frequency of action potentials.
