Electrophysiology

Electrophysiology is the science and branch of physiology that pertains to the flow of ions in biological tissues and, in particular, to the electrical recording techniques that enable the measurement of this flow and the potential changes (signals) related to them. In almost all cases, electrophysiological techniques record the voltage maintained across a cell membrane (i.e. the electrical potential difference between the inside and outside of a cell) or the ion currents that flow across a cell membrane (i.e. the movement of ions from the inside of the cell to the outside or vice versa). The term electrophysiology is used to describe both a scientific discipline (the study of the electrical properties of biological cells) and also a methodological approach (the means to study the electrical properties of biological cells). Each of these aspects of electrophysiology will be dealt with here, in turn.
