Somatosensory evoked potentials after stimulation of the median nerve were obtained in a group of normal individuals. The components obtained between 12 and 22 ms were analysed with cephalic and non-cephalic references. It is shown that the P13-14 complex is the major contributor for the amplitude of the N13 component recorded with electrodes between the posterior neck and the scalp. It has not been possible to detect differences in amplitude or latencies for the components N18 and P22 recorded between FZ-non cephalic and C6-FZ. Implications of these findings to clinical interpretations of the responses are discussed.
在一组正常个体中获得了刺激正中神经后的体感诱发电位。使用头部和非头部参考电极对12至22毫秒之间获得的成分进行了分析。结果表明，P13-14复合波是在后颈部和头皮之间电极记录的N13成分振幅的主要贡献者。未能检测到在FZ-非头部和C6-FZ之间记录的N18和P22成分在振幅或潜伏期上的差异。讨论了这些发现对反应临床解释的意义。
