The early somatosensory evoked potential secondary to median nerve stimulation in the human had an onset latency of 9--12 msec when recorded from scalp electrodes at vertex-to-mastoid, vertex-to-inion or at the base of the skull. Similar latencies were observed from responses recorded over the cervical dorsal columns during neurologic surgery. A latency difference of 1.5 msec was observed between the early response and the responses recorded from the junction of medial lemniscus and nucleus ventralis posterior lateralis of the thalamus during human stereotaxic surgery. Cervical cord transections and transection at the midpontine levels of the monkey showed that the evoked potential was due to generators between these levels. Depth recording of the monkey indicate that the early evoked potential originates in the region of dorsal column nuclei, while the later components are secondary to generators in cerebral cortex.
在人体中，当中枢神经受到刺激时，通过头顶至乳突、头顶至枕外隆凸或颅底的头皮电极记录到的早期体感诱发电位起始潜伏期为9 - 12毫秒。在神经外科手术期间，在颈髓后柱记录到的反应也观察到了类似的潜伏期。在人体立体定向手术中，早期反应与在丘脑内侧丘系和腹后外侧核交界处记录到的反应之间观察到1.5毫秒的潜伏期差异。对猴子进行颈髓横断和脑桥中部横断显示，诱发电位是由这些水平之间的发生器产生的。对猴子的深度记录表明，早期诱发电位起源于背柱核区域，而后期成分则继发于大脑皮层中的发生器。
