摘要： 事件相关电位作为一种特殊的诱发电位发展迅速,为近年来研究人的认知功能最有效的方法之一。P300是事件相关电位中被研究最为广泛和成熟的一个成分,与注意、记忆等高级心理活动过程关系密切。对脑损伤后认知功能改变的评价是这类研究的重点之一,随着相关研究的展开,这项技术在法医临床、精神病等领域将有更加广阔的应用前景。

Abstract: Event-related potentials (ERPs) develop promptly as one kind of special evoked potentials. And it is one of the most effective methods to investigate human′s cognition function in these years. P300 is the component of ERPs which is widely and maturately researched and has intimate relation with attention, memory and other high psychological activity. The evaluation of recognition change after brain injury is the focus of the research. With the development of relatively research, it is deemed that this technique has wide application perspective in many aspects such as forensic clinical medicine and forensic psychiatry.
