title: Sleep telemetry in the rat: I. a miniaturized FM--AM transmitter for EEG and EMG.
abstract: The article describes a miniature 2-channel FM-AM transmitter for recording EEG and EMG in unrestrained, small animals. Field changes during head movements yield a signal which can serve as a measure of motor activity.
