Summary The effect of previous antidromic conditioning of reciprocally inhibited monosynaptic flexor and extensor reflexes was found to depend on the ventral root chosen. Use of a part of the root in which the test reflex was found led to increased inhibition, use of a neighboring root to disinhibition. It is suggested that Renshaw cells in the agonist pool inhibit only those Ia inhibitory interneurons which affect the antagonist. A model for the interconnection of Renshaw cells, Ia inhibitory interneurons and the antagonistic motoneuron pools is proposed which fits not only the results presented here, but also those on single units. The results indicate the presence of occlusion of inhibitory effects and support the assumption that these effects are distributed uniformly within a motoneuron pool.
