title: Identification of muscle spindle afferents during in vivo recordings in man.
abstract: A preamplifier for use in microelectrode recordings from human muscle afferents is described. Electrical stimuli can be delivered through the microelectrode to produce the twitch contractions necessary for afferent identification while still recording the activity of the afferent fibre.
