Supraspinal inhibition of trigeminal input into subnucleus caudalis by dorsal column stimulation.
In decorticate-decerebellate cats with cervical spinal cuts which isolated the dorsal columns (DCs), conditioning volleys travelling in the DCs inhibited activities of trigeminal caudalis neurons. This inhibition was most likely mediated through a brainstem loop and was particularly effective on nociceptive-driven neurons.
