The neocortex ( Latin for "new bark " or "new rind "), also called the neopallium ("new mantle ") and isocortex ("equal rind"), is a part of the brain of mammals . It is the outer layer of the cerebral hemispheres , and made up of six layers, labelled I to VI (with VI being the innermost and I being the outermost). The neocortex is part of the cerebral cortex (along with the archicortex and paleocortex , which are cortical parts of the limbic system ).
The human brain has the same general structure as the brains of other mammals , but is larger than any other in relation to body size. Large animals such as whales and elephants have larger brains in absolute terms, but when measured using the encephalization quotient which compensates for body size, the human brain is almost twice as large as the brain of the bottlenose dolphin , and three times as large as the brain of a chimpanzee . Much of the expansion comes from the part of the brain called the cerebral cortex , especially the frontal lobes , which are associated with executive functions such as self-control, planning, reasoning, and abstract thought. The portion of the cerebral cortex devoted to vision is also greatly enlarged in humans. The human cerebral cortex is a thick layer of neural tissue that covers most of the brain. This layer is folded in a way that increases the amount of surface that can fit into the volume available.
The human brain is divided into two hemispheres–left and right. Scientists continue to explore how some cognitive functions tend to be dominated by one side or the other; that is, how they are lateralized . The longitudinal fissure separates the human brain into two distinct cerebral hemispheres , connected by the corpus callosum . The hemispheres exhibit strong, but not complete, bilateral symmetry in both structure and function.
Helmuth Sørensen Nyborg (born 5 January 1937) is a former professor of developmental psychology at Aarhus University , Denmark . His main research topic is the connection between hormones and intelligence . Among other things, he has worked on increasing the intelligence of girls with Turner's syndrome by giving them estrogen . His research has been widely criticized, and in 2007, after having been accused of scientific misconduct , he received a warning from Aarhus University for producing research of unacceptably low quality.
