CHAPTER 4 STRUCTURE AND CELL BIOLOGY OF THE NEURON
... When a neuron is not receiving any input there is a potential difference (voltage) between the inside and outside of the cell. This voltage is just like the voltage you would measure between two poles of a flashlight battery, but tiny, only a few thousandths of a volt (i.e., a few millivolts). The p ...
