Thoracic nerves refer to the 12 pairs of nerves that originate from the dorsal and ventral roots of the corresponding thoracic segments.

Both in the laboratory with controlled, defined stimuli and in the clinic, a highly variable relationship is observed between the stimulus and the response. Pain differs radically from such sensory experiences as the detection of light or sound where the great majority of the population obey predictable rules.
