Event-related bioelectrical brain activity plays an important role in psychophysiological investigations of mental processes. One of the so-called endogenous components of ERP, the P300, occurring in the time range from 300 ms to 800 ms after stimulus presentation accompanies the selective call on cognitive processing of stimulus information. An overview of some influencing factors and of hypotheses according functional significance of P300 is given. Although functional significance of P300 is only partly known there are interesting possibilities of application, e.g. in Neurology, Psychiatry and Occupational medicine.
与事件相关的脑生物电活动在心理过程的心理生理学研究中起着重要作用。ERP的所谓内源性成分之一，即P300，在刺激呈现后300毫秒至800毫秒的时间范围内出现，伴随着对刺激信息认知加工的选择性调用。本文给出了一些影响因素的概述以及根据P300功能意义提出的假设。尽管P300的功能意义仅部分为人所知，但仍有一些有趣的应用可能性，例如在神经病学、精神病学和职业医学领域。
