Abstract

The event-related potentials (ERP) in frontal and posterior associative cortex in right and left hemispheres were studied in two different outcomes of a television tennis game. These outcomes were 'win' and 'loss' of the ball, the first serving as a model of positive, the second as a model of negative emotional reactions. The ERPs consisted of 4 waves: P300, N600, P800, N1000. The most characteristic interhemispheric difference for 'win' was an increase of N600 in the left posterior associative cortex, and for 'loss', a decrease of P800 in the right frontal area. Thus, the positive and negative emotional reactions have specific spatio-temporal cortical organizations. The topography of ERP related to positive and negative emotions was disturbed in depressive patients. The patients revealed a larger negativity of the right posterior associative cortex and the left frontal cortex waves both at winning and losing the ball.

摘要

研究人员在一场电视网球比赛的两种不同结果中，对左右半球额叶和后联合皮层的事件相关电位（ERP）进行了研究。这两种结果分别是“赢球”和“输球”，前者作为积极情绪反应的模型，后者作为消极情绪反应的模型。ERP由4种波组成：P300、N600、P800、N1000。“赢球”时最具特征性的半球间差异是左后联合皮层N600增加，“输球”时则是右额叶区域P800减少。因此，积极和消极情绪反应具有特定的时空皮层组织。抑郁症患者中，与积极和消极情绪相关的ERP地形图受到干扰。患者在赢球和输球时，右后联合皮层和左额叶皮层的波均显示出更大的负性。
