越来越多的功能和进化研究强调了情绪处理对复杂的人类社会认知的重要贡献。因此，人们可能会问，参与情绪处理的神经结构（通常称为边缘结构）是否在人类大脑进化中受到影响。为了解决这个问题，我们进行了广泛的进化分析，多个边缘结构，使用现代系统发育工具。对于这项分析，我们结合了新的体积数据的类人猿（人类和猿）杏仁核和4杏仁核，海马和纹状体，收集使用体视学方法在完整的组织学系列，与先前发表的数据集杏仁核，眶和内侧额叶皮层，和额叶皮层，以及非边缘系统结构，背侧额叶皮层，对比。我们进行了平行分析，使用大型已发表的数据集，包括许多类人猿物种（人类，猿，猴），但更少的类人猿，杏仁核和2杏仁核亚部，海马，皮层，纹状体，隔核。为了解决进化的变化，我们比较了观察到的人类值的预测值从回归运行通过（a）非人类类人猿和（B）非人类类人猿，使用系统发育广义最小二乘回归评估系统发育的影响。与其他类人猿相比，人类的海马体、杏仁核外侧核和眶额皮质的体积分别比猿类的人类半球体积大50%、37%和11%，而内侧和背侧额叶皮质分别比猿类的人类半球体积小26%和29%。与其他类人猿相比，只有人类的纹状体值显著低于预测值。总的来说，这些数据支持这样一种观点，即参与情绪处理的区域不一定是保守的或退化的，甚至可能在最近的人类进化中得到增强。
Increasingly, functional and evolutionary research has highlighted the important contribution emotion processing makes to complex human social cognition. As such, it may be asked whether neural structures involved in emotion processing, commonly referred to as limbic structures, have been impacted in human brain evolution. To address this question, we performed an extensive evolutionary analysis of multiple limbic structures using modern phylogenetic tools. For this analysis, we combined new volumetric data for the hominoid (human and ape) amygdala and 4 amygdaloid nuclei, hippocampus, and striatum, collected using stereological methods in complete histological series, with previously published datasets on the amygdala, orbital and medial frontal cortex, and insula, as well as a non-limbic structure, the dorsal frontal cortex, for contrast. We performed a parallel analysis using large published datasets including many anthropoid species (human, ape, and monkey), but fewer hominoids, for the amygdala and 2 amygdaloid subdivisions, hippocampus, schizocortex, striatum, and septal nuclei. To address evolutionary change, we compared observed human values to values predicted from regressions run through (a) non-human hominoids and (b) non-human anthropoids, assessing phylogenetic influence using phylogenetic generalized least squares regression. Compared with other hominoids, the volumes of the hippocampus, the lateral nucleus of the amygdala, and the orbital frontal cortex were, respectively, 50, 37, and 11% greater in humans than predicted for an ape of human hemisphere volume, while the medial and dorsal frontal cortex were, respectively, 26 and 29% significantly smaller. Compared with other anthropoids, only human values for the striatum fell significantly below predicted values. Overall, the data present support for the idea that regions involved in emotion processing are not necessarily conserved or regressive, but may even be enhanced in recent human evolution.
