Electrical stimulation of the spinal cord at C7D1 evoked triphasic descending spinal cord evoked potentials (DSCEP) from an oesophago-vertebral recording at D8D8 or D1OD1O. Ascending SCEPs (ASCEP) larger and similar in shape were also observed when the orientation of the stimulating and recording dipoles was reversed. Both SCEPs are in part generated by descending and ascending synchronous excitation of neuronal volume-conducted spinal cord dipoles.
在C7D1水平对脊髓进行电刺激，可在D8D8或D1OD1O水平通过食管 - 椎体记录诱发三相下行脊髓诱发电位（DSCEP）。当刺激偶极子和记录偶极子的方向反转时，也可观察到更大且形状相似的上行脊髓诱发电位（ASCEP）。两种脊髓诱发电位部分是由神经元容积传导的脊髓偶极子的下行和上行同步兴奋产生的。
