title: Telemetry of several biological signals from behaving animals.
abstract: A telemetry device is described for recording ECG, EMG, EEG, multiple and single unit activity from central nervous system. It implies the use of a FET input operational amplifier and an FM oscillator. It can be used with different electrodes and in many animal species when behavioral studies and completely unrestrained subjects are requested.
