WebOct 17, 2024 · The velocity of action potentials is crucial for the right timing in information processing and depends on the dynamics of ion channels studding the axon, but also on its geometrical properties. For instance, the velocity increases approximately linearly with the diameter of myelinated axons [ 1 ]. WebNov 17, 2024 · Can action potentials travel backwards? This means, that as the action potential passes forward and causes depolarisation, it cannot flow backwards as there is the influx of potassium. This means it cannot pass backwards, once the impulse is in the axon. Which direction would the action potential travel? greene county health care inc
