biopotentials

Biopotentials are electrical signals generated by the body’s cells, primarily neurons and muscle cells, as they communicate and perform functions. These signals result from the movement of charged particles across cell membranes, creating tiny electrical currents. For example, brain activity produces electrical patterns detectable as EEG signals, while muscle movement creates electrical signals measured during an ECG or EMG. These electrical signals are essential for coordinating bodily functions, enabling us to think, move, and feel. Devices like medical monitors detect biopotentials to assess health, diagnose conditions, or control prosthetics.
