欺骗是一种复杂的认知活动，不同类型的谎言可能来自不同的神经系统。我们首先根据两个维度对谎言进行分类，即谎言是否符合一个连贯的故事，以及它们之前是否被记住，从而研究了这种可能性。功能磁共振成像显示，符合连贯故事的精心排练的谎言比不符合故事的自发谎言在右侧前额叶皮质引起更多的激活，而在前扣带回和后视皮层则出现相反的模式。此外，这两种类型的谎言在前额叶皮质(双侧)、海马旁回(双侧)、右侧楔前核和左侧小脑都比说真话更能激活大脑。至少在一定程度上，不同的神经网络支持不同类型的欺骗。
Deception is a complex cognitive activity, and different types of lies could arise from different neural systems. We investigated this possibility by first classifying lies according to two dimensions, whether they fit into a coherent story and whether they were previously memorized. fMRI revealed that well-rehearsed lies that fit into a coherent story elicit more activation in right anterior frontal cortices than spontaneous lies that do not fit into a story, whereas the opposite pattern occurs in the anterior cingulate and in posterior visual cortex. Furthermore, both types of lies elicited more activation than telling the truth in anterior prefrontal cortices (bilaterally), the parahippocampal gyrus (bilaterally), the right precuneus, and the left cerebellum. At least in part, distinct neural networks support different types of deception.
