As a response to stimulation of the arm nerves an evoked potential can be recorded in the posterior neck region in man. This nuchal evoked potential (NEP) was recorded in three selected patients with A) cervical rib, B) syringomyelia, and C) prolapse of cervical intervertebral disc. Patients A and C had low-amplitudic NEPs with increased latencies when the affected side was stimulated and "normal" NEPs when the unaffected side was stimulated. Patient B had grossly abnormal, polyphasic NEPs (regardless of the side stimulated) but the simultaneously recorded somatosensory evoked potential was "normal". No systematic differences in the parameters of the NEP due to different recording locations on the neck could be observed.
作为对臂神经刺激的反应，在人体的后颈部区域可记录到诱发电位。在三名选定的患者中记录了这种颈部诱发电位（NEP），这些患者分别患有：A）颈肋，B）脊髓空洞症，以及C）颈椎间盘突出症。患者A和C在刺激患侧时NEP波幅低且潜伏期延长，而刺激未患侧时NEP“正常”。患者B的NEP严重异常且多相（无论刺激哪一侧），但同时记录的体感诱发电位“正常”。未观察到由于颈部不同记录位置导致的NEP参数存在系统性差异。
