The Biosignal How-To

This page shows you with the help of YouTube clips how to measure heart activity (ECG), brain waves (EEG), muscle activity (EMG) and other bio-signals.

You will also learn how to to distinguish noise from actual biosignals and will see that often noise is “sold” as a biosignal. These clips will help you to critically evaluate these claims and make up your own mind.

Interpreting biosignals

The clips below take a homourous approach how to interpret biosignals and show that there is no easy route from mental states to, for example, blood pressure and that noise can be mistaken as EEG.
