How Do Neurons Convey Information?
... To explain the electrical signals of a neuron, Julius Bernstein suggested in 1886 that the neuron’s electrical charge has a chemical basis. This suggestion led to the idea that modifications of a neuron’s charge travel along the axon as a wave. Successive waves constitute the message that the neuron ...
