The cerebral cortex, also known as the cerebral mantle, [1] is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals.It is the largest site of neural integration in the central nervous system, [2] and plays a key role in attention, perception, awareness, thought, memory, language, and consciousness.
Layer I, the molecular layer, is the first cortical layer produced during neurogenesis at mice at embryonal days 10.5 to 12.5 (E10.5 to E12.5). [7] Of the six layers found within the neocortex, layer I is the most superficial and is composed of Cajal–Retzius cells and pyramidal cells. [8]
The mammalian cerebral cortex, the grey matter encapsulating the white matter, is composed of layers.The human cortex is between 2 and 3 mm thick. [11] The number of layers is the same in most mammals, but varies throughout the cortex.
The cerebellar cortex is the thin gray surface layer of the cerebellum, consisting of an outer molecular layer or stratum moleculare, a single layer of Purkinje cells (the ganglionic layer), and an inner granular layer or stratum granulosum. The cortex is the outer surface of the cerebrum and is composed of gray matter. [1] The motor areas are ...
The largest part of the cerebral cortex is the neocortex, which has six neuronal layers. The rest of the cortex is of allocortex, which has three or four layers. [7] The cortex is mapped by divisions into about fifty different functional areas known as Brodmann's areas. These areas are distinctly different when seen under a microscope. [22]

The outer granular layer (layer II) is a major layer of the basic tectogenetic pattern, present over the whole extent of the cortex during foetal life and infancy. It stands out clearly as a thick, compact cellular lamina deep to the cell-spare molecular layer layers, as can be observed in Figures 1 to 3, 8 to 11 and 13 to 15 from man, cat, and ...
A cortical minicolumn (also called cortical microcolumn [1]) is a vertical column through the cortical layers of the brain. Neurons within the microcolumn "receive common inputs, have common outputs, are interconnected, and may well constitute a fundamental computational unit of the cerebral cortex ".
