Mushroom bodies are the insect equivalent of the human neocortex , the outer layer of our brain , which handles complex cognition .

昆虫的蘑菇体相当于人类的新皮层即我们大脑的外层，负责处理复杂的认知加工。

Scientists have already established that the neocortex and the mushroom bodies are larger in social species such as humans and wasps , as compared with solitary animals such as bears and lone spiders .

科学家已经确定，社会性物种（如人类和黄蜂）的新皮层和蘑菇体相对较大，而孤立的动物如熊和蜘蛛则较小。

This belief was based , in part , upon the readily evident physical structure of the neocortex , the region of the brain responsible for complex cognitive behaviors .

这种认识部分基于自大脑皮质的物理构造上获取的简单证据，脑部此区域负责复杂的认知行为。

The findings indicate that laminar and columnar properties of the neocortex are not unique to mammals , and may in fact have evolved from cells and circuits in much more ancient vertebrates .

这一发现显示哺乳动物叠层以及阵列结构的大脑皮质特征并非唯一，（这种结构）是从更为古老的脊椎动物的大脑细胞和神经回路那里进化而来的。

Generally speaking , the brains of mammals have long been presumed to be more highly evolved and developed than the brains of other animals , in part based upon the distinctive structure of the mammalian forebrain and neocortex - a part of the brain 's outer layer where complex cognitive functions are centered .

总的来说，长期以来哺乳动物的大脑都被假定比其他动物的大脑进化发展地更加高等，部分缘于其在结构上与众不同的前脑和皮质位于大脑表层的这个部分集中了复杂的认知功能。
