WebExplain how nerve impulses are transmitted along and between neurones Transmitting Along Neurones When a nerve cell is not stimulated, it is in a resting state. During this state, the inside of the axon is relatively more negative than outside of the axon, this is called the resting potential. Web9 jan. 2014 · Since nerve impulses were discovered in the 1950s, scientists have been unable to describe how the sodium channel gets to where it needs to be to initiate these electrical signals.
