The document discusses how differences in signal strength during action potential propagation are influenced by several factors. These include variations in the time required to produce an action potential, the propagation rate, the peak amplitude during depolarization, and the threshold value. It emphasizes that these variations affect how signals are transmitted in the nervous system.

1. Differences in signal strength are produced during action potential propagation by
varying the length of time it requires to produce an action potential.
varying the rate at which action potentials are propagated.
varying the peak that each action potential reaches during depolarization.
varying the threshold value
