新皮质（拉丁语：neocortex，拉丁文：neo：新的，cortex：皮）是哺乳动物大脑的一部分，在脑半球顶层，大约2-4毫米厚，分为六层，为大脑皮质的一部分。其于一些高等功能如知觉，运动指令（motor commands）的产生，空间推理，意识及人类语言有关系。

The neocortex (Latin for "new bark" or "new rind"), also called the neopallium ("new mantle") and isocortex ("equal rind"), is a part of the mammalian brain. In the human brain, it is the largest part of the cerebral cortex which covers the two cerebral hemispheres, with the allocortex making up the rest. The neocortex is made up of six layers, labelled from the outermost inwards, I to VI. In humans, the neocortex is involved in higher functions such as sensory pe****tion, generation of motor commands, spatial reasoning, conscious thought and language. There are two types of cortex in the neocortex – the true isocortex and the proisocortex.
