J.Y. Lettvin and P.C. Dell (Introduced by W.S. McCulloch)
We have previously shown that the suppressor bulbar reticular fibers in the ventrolateral fasciculus terminate in the internuncial nucleus of the Lateral Column of Ramón y Cajal (the Tractus Cellularum Intercornualis Lateralis of Jacobsohn) and that stimulation here inhibits and only inhibits the motoneurons even when the current is strong enough to excite initially the motoneurons themselves. We now show that this inhibition is accompanied by a long positive potential in the motoneuron pool resembling the positive ‘synaptic potential’ recorded by Eccles with intersegmental reflex inhibition.
