Ever since humanity split into dog and cat people, we've been arguing over which one of our beloved companions is a smarter species. 自从人类分裂为汪星人和喵星人，我们就一直在争论，在这两种备受喜爱的伙伴中，哪种更聪明。 A study from 2017 mightn't be the last word on the matter, but for those who think more neurons means more intelligence, it looks as if dogs stand out among carnivores for having a remarkably dense cerebral cortex. 2017年的一项研究可能无法给这件事下最终定论，但是对于那些认为神经元越多就越聪明的人来说，似乎在肉食动物中，狗出类拔萃，因为狗的大脑皮层神经元十分密集。 An international team of researchers analysed the wrinkled outer layers of the brains of a variety of carnivorous animals - including dogs and cats - to determine whether the demands of hunting prey mean a higher count of cortical neurons, adding brain power where it counts. 一个国际研究员小组分析了多种食肉动物的大脑褶皱外层，包括狗和猫，以此判断捕猎的需求是否意味着皮质神经元比例更高，增加有需要的地方的脑力。 |
