Primary source abstract:"To rectify this deficiency, the conduction velocities of the fastest muscle and cutaneous afferents were determined for the median, ulnar and tibial nerves of normal subjects. Low-threshold muscle afferents innervating abductor pollicis brevis, abductor digiti minimi and abductor hallucis were stimulated selectively through a microelectrode inserted percutaneously at the motor point. Low-threshold cutaneous afferents were stimulated with ring electrodes around the proximal phalanx of digits II or V for the upper limb and digit II for the lower limb. Compound action potentials were recorded with bipolar near-nerve electrodes at two sites in the proximal limb segment and conduction velocities of the fastest afferents in the neural volley calculated." |

2nd paragraph:"...whereas for touch, the brain may have to take into account where the stimulation originated from as the traveling time from the toes to the brain is longer than from the nose (the typical conduction velocity is 55 m/s, which results in a ∼30 ms difference between toe and nose when this distance is 1.60 m primary source)." |
