The wave P300 was recorded in both hemispheres in order to study interhemispheric differences in the process of perception of unrecognized verbal stimuli. The stimuli--unrecognized words, neutral and emotional--were alternately presented at random in the left and right visual fields. In response to an unrecognized emotional word, the amplitude of the P300 wave increases diffusely in both hemispheres, as compared to the response to a neutral word, with no changes in interhemispheric differences. They change considerably in the process of an "unaccountable" emotion, caused by an unrecognized word, due to unilateral activation of the right hemisphere. The conclusion is made on the predominant role of the right hemisphere in the cortical organization of such unconscious function as "unaccountable" emotion.
记录双侧半球的P300波，以研究未识别言语刺激感知过程中的半球间差异。刺激物——未识别的单词，包括中性和情感性的——在左、右视野中交替随机呈现。与对中性词的反应相比，对未识别的情感词的反应中，P300波的振幅在双侧半球均呈弥漫性增加，半球间差异无变化。在由未识别单词引起的“无法解释”的情绪过程中，由于右半球的单侧激活，半球间差异会发生显著变化。得出的结论是，右半球在诸如“无法解释”的情绪这种无意识功能的皮质组织中起主要作用。
