大脑的“默认系统”被描述为一组区域，这些区域在休息时被“激活”，在认知上费力的任务时被“失活”。为了调查任务相关失活的可靠性，我们对12项fMRI研究进行了荟萃分析。我们的结果复制了之前的发现，将内侧额叶和顶叶脑区作为“默认系统”的一部分。然而，这些失活的认知关联仍不清楚。鉴于社会认知能力对人类的重要性及其参与此类活动的倾向，我们将我们的结果与社会认知的神经成像研究结果联系起来。这表明，通常参与社会认知过程的大脑区域和“默认系统”之间存在显著重叠。从此以后，我们认为大脑的生理“基线”与心理“基线”密切相关：人类对社会认知的倾向是默认认知模式，而这种认知模式是在被称为“默认系统”的大脑内部活动的强大模式中实现的。(C)2008 Elsevier Inc.保留所有权利。
The "default system" of the brain has been described as a set of regions which are 'activated' during rest and 'deactivated' during cognitively effortful tasks. To investigate the reliability of task-related deactivations, we performed a meta-analysis across 12 fMRI studies. Our results replicate previous findings by implicating medial frontal and parietal brain regions as part of the "default system".However, the cognitive correlates of these deactivations remain unclear. In light of the importance of social cognitive abilities for human beings and their propensity to engage in such activities, we relate our results to findings from neuroimaging studies of social cognition. This demonstrates a remarkable overlap between the brain regions typically involved in social cognitive processes and the "default system".We, henceforth, suggest that the physiological 'baseline' of the brain is intimately linked to a psychological 'baseline': human beings have a predisposition for social cognition as the default mode of cognizing which is implemented in the robust pattern of intrinsic brain activity known as the "default system".
