P30 0是一种特殊的诱发电位 ,可作为评价认知功能的客观指标。本文不仅对汉族儿童进行了P30 0检测 ,而且对少数民蔟 (藏族、维吾尔簇、哈萨克族 )共 4种民族进行测定 ,研究是否由于文化背景、环境、地理条件等有不同 ,而在民族之间认知功能存在差异。采用声刺激诱发电位 ,靶与非靶二类不同音调声音刺激。结果表明 :民族之间P30 0潜伏期差异无显著意义 (P >0 .0 5 ) ,P30 0检测可以代表受试者认知的真实水平 ,它能客观敏锐地窥知脑功能的状态 ,P30 0潜伏期的变化在评价儿童认知功能方面提供了客观的电生理指标。
P30 0 is a special evoked potential that can be used as an objective measure of cognitive function. This article not only tested P30 0 for Han children, but also measured 4 ethnic minorities (Tibetan, Uygur and Kazak) in ethnic minorities (Han, Uygur and Kazak ethnic groups) to study whether they were different due to cultural background, environment and geographical conditions, There are differences between cognitive functions. The use of acoustic stimulation evoked potentials, target and non-target two different types of pitch sound stimulation. The results showed that there was no significant difference in P30 0 latency among ethnic groups (P> 0.05). The P30 0 test could represent the true level of cognition in subjects. It could objectively and keenly perceive the state of brain function, P30 0 Changes in latency provide objective electrophysiological indicators in evaluating children’s cognitive function.
