Inhibition of dorsal column nuclei by stimulation of trigeminal afferents in decerebrate-decerebellate cats.
In decerebrate-decerebellate cats, stimulation of trigeminal afferents inhibited neurons in dorsal column (DC) nuclei driven by activation of DC input and produced primary afferent depolarization in DC primary afferent terminals. This inhibition was most likely mediated by a trigeminal-brainstem-DC nuclear loop.
