隐匿信息，即只有自己知道的信息，有时对于刑事调查至关重要。在这项研究中，我们检查了与隐藏信息的偶然反应相关的皮层激活。我们发现，皮质对与隐藏信息相关的刺激的反应不同于对其他刺激的反应。双侧腹外侧前额叶（VLPF）区域、左侧额下回、右侧额中回和右侧顶下小叶被激活，其中右侧VLPF至关重要。此外，我们通过判别分析检查了哪些皮质区域有助于确定受试者是否隐藏了信息。根据右侧 VLPF 的活动，我们能够正确识别 38 名受试者中的 32 名 (84.21%) 是否隐瞒了信息。这些结果表明，正确的 VLPF 可能在隐藏信息的附带处理中发挥着至关重要的作用，我们能够确定受试者是否隐藏了信息，而不需要做出欺骗性的反应。
Concealed information, which is information only known to oneself is sometimes crucial for criminal investigation. In this study, we examined cortical activations related to incidental responses to concealed information. We found that cortical responses to stimuli related to concealed information were different from those to other stimuli; the bilateral ventrolateral prefrontal (VLPF) areas, left inferior frontal gyrus, right middle frontal gyrus and right inferior parietal lobule were activated, and among those activated areas, the right VLPF was found to be crucial. Furthermore, we examined by discriminant analysis which cortical areas contribute to the determination of whether the subjects had concealed information. On the basis of the activity in the right VLPF, we were able to correctly identify 32 of the 38 subjects (84.21%) as who had concealed information. These results suggest that the right VLPF may play a crucial role in the incidental processing of concealed information, and we were able to determine whether a subject had concealed information without the need for deceptive responses.
