Since internuncial neurons run to both Edinger-Westphal nuclei, light input to the normal eye results in signals being sent in the efferent motor neurons to the abnormal and normal eyes.
The pathway continues from the ventral trigeminal nucleus through the short internuncial nerve fibers in the reticular formation in the brain stem to finally synapse on efferent premotor parasympathetic cardioinhibitory neurons in the nucleus ambiguous [2, 3].
Researchers (11), (12) believe that an initial nociceptive afferent stimulation can sensitize a wide range of multireceptive neurons in the spinal internuncial neuron pool that are at the center of an abnormal reflex.
