A simple and effective low cost frequency modulation system for neurophysiological recording.
A frequency modulation system to be used for electrophysiological signal recording on a standard Hifi tape recorder is described. This system can be built using a few common, easy-to-use and cheap integrated circuits. Its performance allows reliable recording of either DC potentials or fast transients (action potentials for instance). Possible uses (EEG, intracellular recording ....) are illustrated. The main advantages of this system are simplicity and low cost.
