以确定神经冲动在活人身上沿着周围神经纤维传播需要多长时间。进行碰撞实验，测量尺神经传导速度分布。远端和近端的两个刺激被用来产生碰撞。记录复合肌肉或神经动作电位，分别对运动神经和混合神经进行测量。刺激间期设定为1~5ms。采用四脉冲技术测量不应期并校准传导时间。近端刺激产生的复合肌肉动作电位在刺激间隔1.5ms左右开始出现，并随着刺激间隔的增加而增加。鉴定出两组不同传导速度的运动神经纤维。混合神经比运动神经具有更宽的传导速度分布，可识别更多的神经纤维亚群。周围运动和混合神经在高分辨率下的传导速度分布是不同的，这可以用碰撞试验来测量。我们提供了地面真实数据，以验证用于测量周围神经系统潜伏期连接体的神经成像管道。
To determine how long it takes for neural impulses to travel along peripheral nerve fibers in living humans. A collision test was performed to measure the conduction velocity distribution of the ulnar nerve. Two stimuli at the distal and proximal sites were used to produce the collision. Compound muscle or nerve action potentials were recorded to perform the measurements on the motor or mixed nerve, respectively. Interstimulus interval was set at 1–5 ms. A quadri-pulse technique was used to measure the refractory period and calibrate the conduction time. Compound muscle action potential produced by the proximal stimulation started to emerge at the interstimulus interval of about 1.5 ms and increased with the increment in interstimulus interval. Two groups of motor nerve fibers with different conduction velocities were identified. The mixed nerve showed a wider conduction velocity distribution with identification of more subgroups of nerve fibers than the motor nerve. The conduction velocity distributions in high resolution on a peripheral motor and mixed nerve are different and this can be measured with the collision test. We provided ground truth data to verify the neuroimaging pipelines for the measurements of latency connectome in the peripheral nervous system.
