Abstract：
Cross-species research has advanced human understanding of brain regions, with cross-species comparisons using magnetic resonance imaging technology becoming increasingly common. Currently, cross-species research on human language regions has primarily focused on traditional brain areas such as the Broca region. While some studies have indicated that human language function also involves other language regions, the corresponding relationships between these brain regions in humans and macaques remain unclear. This study calculated the strength of the connections between the high-level language processing regions in human and macaque brains, identified homologous target areas based on the structural connections of white-matter fiber bundles, and compared the connectivity profiles of both species. The results of the experiment demonstrated that macaques possess brain regions which exhibit connectivity patterns resembling those found in human high-level language processing regions. This discovery suggests that while the function of a human brain region is specialized, it still maintains a structural connectivity similar to that seen in macaques.
摘要：
跨物种研究提高了人类对大脑区域的理解，随着使用磁共振成像技术的跨物种比较变得越来越普遍。目前,关于人类语言区域的跨物种研究主要集中在传统的大脑区域，例如Broca区域。虽然一些研究表明人类的语言功能也涉及其他语言区域,人类和猕猴的这些大脑区域之间的对应关系尚不清楚。这项研究计算了人类和猕猴大脑中高级语言处理区域之间的连接强度，根据白质纤维束的结构连接确定同源目标区域，并比较了这两个物种的连通性。实验结果表明，猕猴的大脑区域表现出与人类高级语言处理区域相似的连接模式。这一发现表明，虽然人脑区域的功能是专门的，它仍然保持着与猕猴相似的结构连通性。
