采用电生理标测技术，对5只犬进行了脊髓直接刺激和记录，以识别背根进入区（DREZ）和脊髓背侧和背外侧的长束。从刺激部位远端的部位获得鞘内记录。低强度刺激脊髓背外侧后，最快传导纤维的传导速度高于脊髓背侧刺激后。在特定的刺激强度下，背外侧刺激的诱发反应大于背侧刺激。这种技术在单独使用电生理标准识别DREZ中是有用的。
Direct spinal cord stimulation and recording was performed in five dogs to identify the dorsal root entry zone (DREZ) and long tracts within the dorsal and dorsolateral spinal cord using electrophysiological mapping techniques. Intrathecal recordings were obtained from sites distal to the site of stimulation. Conduction velocity in the fastest conducting fibers was higher following low-intensity stimulation of the dorsolateral spinal cord than after dorsal spinal cord stimulation. The evoked response was larger following dorsolateral than dorsal spinal cord stimulation at a specific stimulus intensity. This technique is useful in identifying the DREZ using electrophysiological criteria alone.
