Main article: Electrophysiology

In biology a signal or biopotential is an electric quantity (voltage or current or field strength), caused by chemical reactions of charged ions. Another use of the term lies in describing the transfer of information between and within cells, as in signal transduction. Biological signals can also be seen as an example of signal (information theory).
