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 .
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 .
