Polarization found in even semi-dead axon (studied dead squids) Resting potential- difference in electrical charge between the inside and the outside of the membrane of a neuron at rest. Scientist wanted to know why and what was causing this. Unequal distribution of ions* on the two sides of the membrane. *atoms or molecules that are + or charged (i. e. lost or acquired elections): A- are stuck on the inside due to having no channel.
