<P> The neocortex, also called the neopallium and isocortex, is the part of the mammalian brain involved in higher - order brain functions such as sensory perception, cognition, generation of motor commands, spatial reasoning and language . </P> <P> The neocortex is further subdivided into the true isocortex and the proisocortex . </P> <P> In the human brain, the neocortex is the largest part of the cerebral cortex which is the outer layer of the cerebrum, with the allocortex making up the rest . The neocortex is made up of six layers, labelled from the outermost inwards, I to VI . Of all the mammals studied to date (including humans), a species of oceanic dolphin known as the long - finned pilot whale has been found to have the most neocortical neurons . </P> <P> Neocortex is Latin for "new bark" or "new rind". Neopallium means "new mantle" and isocortex means "equal rind". </P>
