Features of projections of afferent fibers of the ventral roots to neurons of the dorsal horn of the spinal cord in the cat]

Some peculiarities of afferent effects from ventral roots on the dorsal horn neurons were investigated in acute experiments on cats. Convergence of afferents from ventral and dorsal roots on the same neurons was shown. Excitation of some ventral root afferents caused inhibition in investigated neurons. This inhibition developed with shorter latency than that from dorsal root afferents.
