Fig. 5. Afferents from distal mechanoreceptors causing excitatory postsynaptic potentials (EPSPs) in slow- and fast-depressor motoneurons of muscle M103d. (A) Spikes from a posterior spur afferent evoke EPSPs in the fast-depressor motoneuron. A central latency of 4 ms (mean not shown here) indicates a polysynaptic connection. (B) Tibial hair afferents cause EPSPs in the slow-depressor motoneuron with a central latency of 5 ms, indicating polysynaptic connectivity.
