Animals vary in their dispositions, abilities, and moods and demonstrate characteristic behavior patterns that remain consistent across situation and time. This study describes the relationship between measures of personality in the chimpanzee and the structure of the subgenual cingulate cortex (SGCC). Measures of individual traits and personality factors (dominance, extraversion, conscientiousness, and agreeableness) and assessments of percentage of SGCC gray matter (PGM) and asymmetry taken from MRI scans were obtained for 74 chimpanzees housed at the Yerkes National Primate Research Center. PGM in the SGCC was significantly higher for females than for males and was significantly correlated with two personality factors (dominance and conscientiousness) in male apes. There was also a population-level leftward asymmetry in the SGCC. These results are discussed in terms of current models of SGCC function, which suggest that this area may play a role in the biological foundation of personality.
动物在性格、能力和情绪方面存在差异，表现出一致的特征性行为模式，不受情境和时间的影响。本研究描述了黑猩猩个性测量与扣带回下皮质（subgenual cingulate cortex，SGCC）结构之间的关系。我们从磁共振成像（MRI）扫描中获取了 74 只生活在耶基斯国家灵长类动物研究中心的黑猩猩的个体特征和个性因素（支配性、外向性、尽责性和宜人性）测量值以及 SGCC 灰质百分比（percentage of SGCC gray matter，PGM）和不对称性的评估值。SGCC 的 PGM 女性明显高于男性，且与雄性猿类的两个个性因素（支配性和尽责性）显著相关。SGCC 还存在群体水平的左侧不对称性。这些结果与目前关于 SGCC 功能的模型进行了讨论，该模型表明，该区域可能在个性的生物学基础中发挥作用。
