The one experiment that led to the changes to the original cell theory was the experiment that established the existence of single celled organisms and microbes. 1  Comments. 2  Report.
In the depolarized state, the inside of the cell becomes the positive pole and the outside of the cell becomes the negative pole. The increase in membrane potential created between the inside and the outside of the cell during depolarization is called the action potential. Once a cell is excited (depolarized), it can excite adjacent cells and pass on its action potential, spreading depolarization to more and more cells.
