| 摘 要： | 为探讨不同效价情绪图片的加工特点,考察被试在对不同效价的情绪图片加工时脑半球上的差异,利用脑功能磁共振成像技术,对情绪加工实验的被试进行数据采集,并对采集的数据用统计参数映射技术进行处理分析。研究发现情绪刺激加工的过程中,脑激活区域明显和前额叶,顶叶相关,而且是情绪功能相关联的主要位置。这表明人类情绪的反应并不仅仅是由边缘系统控制,在情绪刺激作用下,整个丘脑系统,边缘系统都参与其中进而形成一本复杂的情绪中枢机制。

| Abstract: | To discuss the emotion processing characteristics of different emotional valance pictures, and study the differences in the cerebral hemisphere under the stimuli of different emotional valance pictures, using the Brain Magnetic Resonance Imaging Technology to collect the data -- in Emotion processing experiments, then the collected data is processed and analyzed with Statistical parametric mapping （SPM） technology. It found that in the course of emotional stimulus processing, the brain active region had obvious relationship with prefrontal and parietal lobe, and it＇s the main position of the emotions associated function. This indicated that the human emotional reaction was not only controlled by the limbic system, under the effects of the emotion stimulus, the whole thalamus system and limbic system were involved, then formed a complex emotion central mechanism. |
