Abstract

1. Responses from de-efferented muscle spindles in sheep extraocular muscles have been recorded in the Gasserian ganglion using glass microelectrodes. 2. The afferent fibre conduction velocities ranged from 32 to 106 m/sec and most were intermediate. The distribution was unimodal. 3. The afferent responses to ramp stretches and longitudinal vibration of the muscle could not be divided into two groups, but both the dynamic indices and vibration sensitivities of the afferents increased with their conduction velocities. 4. Injection of suxamethonium did not help to classify afferents with intermediate conduction velocity. 5. It is concluded that the afferents from sheep extraocular muscle spindles form a single population whose properties are correlated with their nerve fibre diameters.
