Histochemical and electrophysiological procedures were carried out to determine the cell types in the ventral horn which are in close contact with noradrenergic terminals and to identify the types of neurons in the ventral horn which are influenced by noradrenaline (NA). Fluorescence histochemical studies revealed that noradrenaline-containing fibers rarely form intimate contacts with alpha motoneurons, whereas many small interneurons which are closely invested with fluorescent fibers can be found near the motoneurons. The effects of microiontophoretically applied NA on interneurons were examined in the lateral motor areas of the lumbar spinal cord ventral horn. NA had a substantial depressant action on 43% of cells in chloralose-anesthetized and decerebrate cats; it excited 6% of the cells, and was without effect on the rest. The cells which were depressed by NA could be excited by electrical stimulation of high threshold muscle afferents or skin afferents, and they could be influenced from a variety of exteroceptive and proprioceptive inputs. Owing to considerable convergence on the affected interneurons, no distinct population of NA-sensitive interneurons could be identified. Many of the interneurons strongly depressed by NA were found near the motor nuclei. The hypothesis is presented that inhibitory actions of NA on interneurons in the motor nuclei might explain its hyperpolarizing action on motoneurons.
