Generator sources of far-field P30 and N33 components produced by posterior tibial nerve stimulation were compared with those of the P14 and N18 components of median nerve stimulated somatosensory evoked potentials. Intracranial spatio-temporal distributions of P30 and N33 were similar to those of the P14 and N18 obtained by median nerve stimulation. In clinical cases, the changes in P30 and N33 were correlated with those in P14 and N18, indicative that P30 and N33 are derived from activities similar to those that produce P14 and N18.
将胫后神经刺激产生的远场P30和N33成分的发生器来源与正中神经刺激体感诱发电位的P14和N18成分的发生器来源进行了比较。P30和N33的颅内时空分布与正中神经刺激获得的P14和N18的分布相似。在临床病例中，P30和N33的变化与P14和N18的变化相关，表明P30和N33源自与产生P14和N18的活动相似的活动。
