Anatomical terms of neuroanatomy. [edit on Wikidata] In neuroanatomy, the primary somatosensory cortex is located in the postcentral gyrus of the brain 's parietal lobe, and is part of the somatosensory system. It was initially defined from surface stimulation studies of Wilder Penfield, and parallel surface potential studies of Bard, Woolsey ...
The somatosensory system, or somatic sensory system is a subset of the sensory nervous system. It has two subdivisions, one for the detection of mechanosensory information related to touch, and the other for the nociception detection of pain and temperature. [1] The main functions of the somatosensory system are the perception of external ...
68596. Anatomical terms of neuroanatomy. [edit on Wikidata] A Brodmann area is a region of the cerebral cortex, in the human or other [citation needed] primate brain, defined by its cytoarchitecture, or histological structure and organization of cells. The concept was first introduced by the German anatomist Korbinian Brodmann in the early 20th ...
A 2-D model of cortical sensory homunculus. A cortical homunculus (from Latin homunculus 'little man, miniature human' [1] [2]) is a distorted representation of the human body, based on a neurological "map" of the areas and proportions of the human brain dedicated to processing motor functions, and/ or sensory functions, for different parts of the body.
61896. Anatomical terms of neuroanatomy. [edit on Wikidata] In neuroanatomy, the postcentral gyrus is a prominent gyrus in the lateral parietal lobe of the human brain. It is the location of the primary somatosensory cortex, the main sensory receptive area for the sense of touch. Like other sensory areas, there is a map of sensory space in this ...
Located in the parietal lobe, the primary somatosensory cortex is the primary receptive area for the sense of touch and proprioception in the somatosensory system. This cortex is further divided into Brodmann areas 1, 2, and 3. Brodmann area 3 is considered the primary processing center of the somatosensory cortex as it receives significantly ...
S1 is green in the top left, and the supplementary somatosensory area is green in the bottom left. The human secondary somatosensory cortex (S2, SII) is a region of sensory cortex in the parietal operculum on the ceiling of the lateral sulcus. Region S2 was first described by Adrian in 1940, who found that feeling in cats' feet was not only ...
The tissue in the image has been stained with cytochrome oxidase and is 50μm thick. The barrel cortex is a region of the somatosensory cortex that is identifiable in some species of rodents and species of at least two other orders [1] and contains the barrel field. The 'barrels' of the barrel field are regions within cortical layer IV that are ...
