Summary Intracellular recording has been made in spinal cats from more than 100 interneurones in the dorsal horn and intermediary region of the lumbosacral spinal cord. The majority of interneurones receive not only EPSPs but also IPSPs from primary afferents. The IPSPs are evoked from three different systems, group I muscle afferents (probably Ib), low threshold cutaneous afferents and the FRA. The shortest central latency of the IPSPs indicates a disynaptic linkage from primary afferents. Interneurones with monosynaptic EPSPs from group I muscle afferents may receive IPSPs from all the above mentioned afferent systems. Interneurones with monosynaptic EPSPs from cutaneous afferents receive their inhibition from the two latter afferent systems. Convergence of EPSPs and IPSPs from the FRA may occur on the same interneurone. The results are discussed mainly with respect to inhibitory interaction between spinal reflex pathways.
