WebOcular dominance columns are stripes of neurons in the visual cortex of certain mammals (including humans [1]) that respond preferentially to input from one eye or the other. [2] The columns span multiple cortical … 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.

A cortical column is a group of neurons forming a cylindrical structure through the cerebral cortex of the brain perpendicular to the cortical surface. The structure was first identified by Mountcastle in 1957. He later identified minicolumns as the basic units of the neocortex which were arranged into columns. … Ver mais The mammalian cerebral cortex, the grey matter encapsulating the white matter, is composed of layers.
