Brodmann area 43, the subcentral area, is a structurally distinct area of the cerebral cortex defined on the basis of cytoarchitecture. Along with Brodmann Area 1, 2, and 3, Brodmann area 43 is a subdivision of the postcentral region of the brain, [1] suggesting a somatosensory ('feeling of the body') function. The histological structure of ...
It remains one of the earliest methods of analyzing the brain and has allowed researchers to study the relationship between cortical structure and systemic function. [2] Cortical stimulation mapping is used for a number of clinical and therapeutic applications, and remains the preferred method for the pre-surgical mapping of the motor cortex ...
The primary gustatory cortex (G) is located near the somatotopic region for the tongue (S1), in the insular cortex deep in the lateral fissure with the secondary taste areas in the opercula. [ 11 ] The peripheral taste system likely maintains a specific relationship between taste bud cells selectively responsive to one taste quality and the ...
When a stimulus is cognitively associated with reinforcement, its cortical representation is strengthened and enlarged. In some cases, cortical representations can increase two to threefold in 1–2 days at the time at which a new sensory motor behavior is first acquired, and changes are largely finished within at most a few weeks.

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 6 cortex layers migrate from the ventricular zone through the subplate to come to rest in the cortical plate (layers 2 through 6) or in the marginal zone (layer 1) The preplate also contains the predecessor to the subplate, which is sometimes referred to as a layer. As the cortical plate appears, the preplate separates into two components.
Early brain lesion studies indicated that different parts of the cortex served different cognitive functions, such as visual, somatosensory, and motor functions, beautifully assimilated by Brodmann in 1909. [1] Today the field supports the idea of a 'protomap', which is a molecular pre-pattern of the cortical areas during early embryonic stages ...
