Which of the following statements about neural signaling is FALSE?
Action potentials have a refractory period. |
||
The ability to generate action potentials allows one end of a long axon (e.g., 2 meters in length) to receive signals from the other end despite other despite the very short distances (<5 mm) that signals can travel passively along the axon. |
||
The intensity of a signal activating a neuron is coded by the amplitude of the action potentials its axon conducts. |
||
Axons must be depolarized to a threshold voltage level in order to initiate an action potential. |
