biosignal
Sign in to save300px|thumb|Sample synchronized biosignals from a human subject. A biosignal is any signal in a living organism that can be continually measured and monitored. The term biosignal is often used to refer to bioelectrical signals, but it may refer to both electrical and non-electrical signals. The usual understanding is to refer only to time-varying signals, although spatial parameter variations (e.g. the nucleotide sequence determining the genetic code) are sometimes subsumed as well.

== Electrical biosignals == Electrical biosignals, or bioelectrical time signals, usually refers to the change in electric current produced by the sum of an electrical potential difference across a specialized tissue, organ or cell system like the nervous system. Thus, among the best-known bioelectrical signals are: Electroencephalogram (EEG) Electrocardiogram (ECG) Electromyogram (EMG) Electrooculogram (EOG) Electroretinogram (ERG) Electrogastrogram (EGG) Galvanic skin response (GSR) or electrodermal activity (EDA)
