title: Proprioceptive control of a muscle receptor organ in the locust leg.
abstract: In the locust hind leg a muscle receptor organ (MRO) consisting of a single multipolar sensory neuron and a receptor muscle spans the joint between coxa and trochanter. Several other proprioceptors of the same joint exert reflexes onto the single excitatory motoneuron specific to the receptor muscle. The resulting changes in muscular tension in turn strongly affect afferent discharge of the MRO.
