The neocortex, also called the neopallium, isocortex, or the six-layered cortex, is a set of layers of the mammalian cerebral cortex involved in higher-order brain functions such as sensory perception, cognition, generation of motor commands, spatial reasoning and language. The neocortex is further subdivided into the true isocortex and the proisocortex. WebJon H. Kaas, in Contributions to Sensory Physiology, 1995 1 Columns. A precise and rather rigid definition of a cortical column might serve as a useful starting point for discussion. …

Web1 de jan. de 2014 · Columns with similar response properties are often connected by long-range horizontal connections. Numerous efforts have been undertaken to develop computational models of the cortical column, which is often equated with the quest to identify the fundamental computational unit of the mammalian brain. WebIt is therefore necessary to investigate each neuronal connection individually, in order to develop a realistic model of neuronal connectivity and organization of a cortical column.
