| Abstract: | In decorticate-decerebellate cats with cervical spinal cuts which isolated the dorsal columns (DCs), conditioning volleys travelling in the DCs inhibited activities of trigemenal caudalis neurons. This inhibition was most likely mediated through a brainstem loop and was particularly effective on nociceptive-driven neurons. |
| Keywords: | dorsal column stimulation trigeminal caudalis neuron brainstem tooth pulp stimulation nociception |
