WebNeurons have a negative concentration gradient most of the time, meaning there are more positively charged ions outside than inside the cell. This regular state of a negative concentration gradient is called resting membrane potential. During the resting membrane … WebMembrane potentials result from a separation of positive and negative charges (ions) across the membrane, similar to the plates within a battery that separate positive and negative charges. Membrane potentials in cells are determined primarily by three factors: 1) the concentration of ions on the inside and outside of the cell; 2) the ...
