In a number of cases, brain areas are organized into topographic maps, where adjoining bits of the cortex correspond to adjoining parts of the body, or of some more abstract entity. A simple example of this type of correspondence is the primary motor cortex, a strip of tissue running along the anterior edge of the central sulcus. Motor areas ...
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.
The primary visual cortex (V1, Brodmann's area 17) is the first cortical area to receive visual input. The stria of Gennari – a set of heavily myelinated, horizontally projecting axons within the termination zone of lateral geniculate nucleus (LGN) input to V1 – provides an anatomical marker particular to V1.
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 ventrolateral prefrontal cortex is important for the regulation of meaningful stimuli that a person experiences throughout their lifetime, such as images, letters, and names. Damage to the prefrontal cortex can result in issues with one's long term and short-term memories, as well as create changes in people's behaviors and their abilities ...
Brodmann areas 41 and 42 are parts of the primary auditory cortex.. Brodmann area 41 is also known as the anterior transverse temporal area 41 (H). It is a cytoarchitectonic division of the cerebral cortex occupying the anterior transverse temporal gyrus (H) in the bank of the lateral sulcus on the dorsal surface of the temporal lobe.
These areas are differentiated from the more anterior area 11 by a lack of continuous granular layer, [2] and from the more posterior agranular Insular cortex. [3] Area 13b is a thin and dysgranular cortical area, often characterized by crossing patterns of striations in layers III and V. Area 13a has an agranular structure.
