论文摘要
一项关于灵长类动物的研究确定，陀螺大小在很大程度上与整体大脑大小无关。在此基础上，以及其他研究表明大脑旋转可能会减轻头部影响的影响，我们的研究旨在探索陀螺大小和头部影响风险之间的潜在相关性。我们的发现证实了回旋大小在很大程度上独立于大脑大小的观念，尤其是在大脑较大的物种中，因此将这种观察结果扩展到了灵长类动物之外。初步证据还表明，动物的陀螺大小与其生活方式之间存在相关性，尤其是在头部影响风险方面。例如，山羊以其头撞行为而闻名，表现出较小的陀螺尺寸。相比之下，通常面临较低头部撞击风险的海牛和矮人等物种具有脑脑的大脑。此外，我们探索了可能解释较窄的陀螺尺寸如何提供防止头部影响的保护优势的机制。最后，我们讨论了与gyrencephaly相关的可能的权衡。
A study on primates has established that gyral size is largely independent of overall brain size. Building on this, and other research suggesting that brain gyrification may mitigate the effects of head impacts, our study aims to explore potential correlations between gyral size and the risk of head impact across a diverse range of mammalian species. Our findings corroborate the idea that gyral sizes are largely independent of brain sizes, especially among species with larger brains, thus extending this observation beyond primates. Preliminary evidence also suggests a correlation between an animal's gyral size and its lifestyle, particularly in terms of head-impact risk. For instance, goats, known for their headbutting behaviors, exhibit smaller gyral sizes. In contrast, species such as manatees and dugongs, which typically face lower risks of head impact, have lissencephalic brains. Additionally, we explore mechanisms that may explain how narrower gyral sizes could offer protective advantages against head impact. Finally, we discuss a possible trade-off associated with gyrencephaly.
