Excitation of neurons depends on the selected influx of certain ions through specific channels. Obviously, these channels were crucial for the evolution of nervous systems in animals. Scientists have revealed that voltage-gated sodium channels, which are responsible for neuronal signaling in the nerves of animals, evolved twice in higher and lower animals.
