Membrane voltage in slow and fast firing Purkinje cells

8 Sep 2020

Cell membranes have a voltage across them due to the uneven distribution of charged particles, called ions, between the inside and outside of the cell. Neurons can shuttle ions across their membrane through channels and pumps, which changes the voltage of the membrane. Fast firing Purkinje neurons have a higher membrane voltage than slow firing neurons.
