在这项研究中，我们调查了大脑系统在忽略情绪显著信息和忽略非情绪信息时的差异程度。该设计允许在颜色词和情绪Stroop任务期间使用功能磁共振成像检查区域大脑活动。12名参与者指出了颜色的话，而忽略了词的意义的条件下，中性词相比，情绪消极，情绪积极，不一致的颜色词。背外侧额叶活动增加了消极和不一致的颜色词，表明一个共同的系统，保持注意力集中的存在显着的干扰。在大脑的后部区域，活动取决于被忽略的信息的性质。忽略颜色不一致的话增加左顶叶的活动和减少海马旁回的活动，而忽略负面情绪的话增加双侧枕颞叶的活动和减少杏仁核的活动。结果表明，情绪和注意力密切相关，通过网络的区域，监测显着的信息，保持注意力的任务，抑制无关的信息，并选择适当的反应。
In this research, we investigated the degree to which brain systems involved in ignoring emotionally salient information differ from those involved in ignoring nonemotional information. The design allowed examination of regional brain activity, using fMRI during color-word and emotional Stroop tasks. Twelve participants indicated the color of words while ignoring word meaning in conditions in which neutral words were contrasted to emotionally negative, emotionally positive, and incongruent color words. Dorsolateral frontal lobe activity was increased by both negative and incongruent color words, indicating a common system for maintaining an attentional set in the presence of salient distractors. In posterior regions of the brain, activity depended on the nature of the information to be ignored. Ignoring color-incongruent words increased left parietal activity and decreased parahippocampal gyrus activity, whereas ignoring negative emotional words increased bilateral occipito-temporal activity and decreased amygdala activity. The results indicate that emotion and attention are intimately related via a network of regions that monitor for salient information, maintain attention on the task, suppress irrelevant information, and select appropriate responses.
