The detection of evoked cortical potentials to a peripheral stimulus is a possible method of studying sensory innervation in children. The purpose of the present study was to determine the consistency with which evoked responses to the electrical stimulation of nerve trunks can be recorded, and to assess the validity of computer analysis of the records. Automated analysis was felt to be desirable because the identification of evoked potentials is usually subjective. Recording sessions were carried out on 37 normal children between the ages of one and six months, and where possible were repeated on three occasions at intervals of at least one month. Using a rigid recording regime, evoked responses could be obtained in 90 to 95 per cent of sessions, the success rate varying with the site of stimulation. An objective computer analysis of records has been developed which is able to recognise evoked potentials as successfully as an experienced human observer.
检测外周刺激诱发的皮层电位是研究儿童感觉神经支配的一种可行方法。本研究的目的是确定记录神经干电刺激诱发反应的一致性，并评估记录的计算机分析的有效性。由于诱发电位的识别通常是主观的，因此认为自动分析是可取的。对37名年龄在1至6个月之间的正常儿童进行了记录，并且在可能的情况下，至少间隔1个月重复进行3次。采用严格的记录方法，在90%至95%的记录中可以获得诱发反应，成功率因刺激部位而异。已经开发出一种对记录进行客观计算机分析的方法，其识别诱发电位的成功率与经验丰富的人类观察者相当。
