大脑结构、大脑功能和行为之间的关系是神经科学、进化生物学和心理学的主要兴趣。当考虑到类人猿特有的大脑结构时，这种关系尤其有趣，因为它们不能在神经科学中广泛研究的模型中进行研究，如小鼠，绒猴和猕猴。梭状回（FG）是一个原始人特有的结构，对面部处理至关重要，在发育性面孔失认症（DP）患者中是异常的-在没有脑损伤的情况下，识别熟悉人的面孔有严重缺陷的人。虽然以前的研究已经发现DP和NT之间FG的解剖和功能差异，但没有研究研究检查FG内的浅三级沟（中梭状沟，MFS），该沟是人类的显微解剖，宏观解剖和功能标志，并且最近被证明存在于非人类类人猿中。在这里，我们实现了神经解剖学和面部感知的NT和DP的预注册分析。结果表明，DP的MFS短于NT。此外，MFS长度的个体差异在右侧，但不是左侧，大脑半球预测个人差异的面孔知觉。这些结果支持将大脑结构和功能与感知联系起来的理论，并表明MFS长度的个体差异可以预测面部处理的个体差异。最后，这些研究结果增加了越来越多的证据支持后期发展，三级沟和认知的个体差异的形态变异之间的关系。
The relationship among brain structure, brain function, and behavior is of major interest in neuroscience, evolutionary biology, and psychology. This relationship is especially intriguing when considering hominoid-specific brain structures because they cannot be studied in widely examined models in neuroscience such as mice, marmosets, and macaques. The fusiform gyrus (FG) is a hominoid-specific structure critical for face processing that is abnormal in individuals with developmental prosopagnosia (DPs)—individuals who have severe deficits recognizing the faces of familiar people in the absence of brain damage. While previous studies have found anatomical and functional differences in the FG between DPs and NTs, no study has examined the shallow tertiary sulcus (mid-fusiform sulcus, MFS) within the FG that is a microanatomical, macroanatomical, and functional landmark in humans, as well as was recently shown to be present in non-human hominoids. Here, we implemented pre-registered analyses of neuroanatomy and face perception in NTs and DPs. Results show that the MFS was shorter in DPs than NTs. Furthermore, individual differences in MFS length in the right, but not left, hemisphere predicted individual differences in face perception. These results support theories linking brain structure and function to perception, as well as indicate that individual differences in MFS length can predict individual differences in face processing. Finally, these findings add to growing evidence supporting a relationship between morphological variability of late developing, tertiary sulci and individual differences in cognition.
