中文摘要：
针对返回抑制（IOR）脑电研究中线索和靶的交互影响,提出了利用低分辨率源定位算法对外源线索所诱发的源进行定位。结果显示相关神经活动可分为3个阶段：早阶段主要在前额叶皮层、顶内皮层和对侧枕颞皮层;中阶段在额叶皮层和顶部皮层;晚阶段在同侧顶枕部皮层。上述结果表明,IOR的产生与两个神经网络有关,并支持IOR与注意和动作反应抑制都相关。
英文摘要：
To avoid the interaction between the cue and the target on the electroencephalogram（EEG） study of inhibition of return（IOR）,the low-resolution electromagnetic（LORETA） algorithm is used to localize the source after an exogenous cue in this work.The results show that activations may be divided into three stages.In the early stage,activations are in the prefrontal cortex,the intraparietal cortex,and the contralateral occipito-temporal cortex.In the middle stage,activations are in the frontal cortex and the parietal cortex.In the late stage,activations are in the ipsilateral occipito-parietal cortex.These findings indicate that the generation of IOR includes two neural networks,and support that IOR is related to both attention and motor response inhibition.
