primary somatosensory cortex

primary somatosensory cortex (S1)

The term primary somatosensory cortex refers to a part of cerebral cortex defined on the basis of multiple histologic criteria and identified with the mediation of sensations originating from the skin, muscles and joints of the body ( Kaas-2004 ). The area was mapped functionally by evoked potentials to light touch in several mammalian species ( Woolsey-1958 ). In the human and macaque it is located in the postcentral gyrus of the parietal lobe ( Carpenter-1983 ) and is commonly referred to as the anterior parietal cortex ( Kaas-2012 ). In the human, proceeding caudally from the central sulcus, it is identified with the cytoarchitecturally defined area 3a of Vogts, area 3b of Vogts, area 1 of Brodmann (human) and area 2 of Brodmann (human) ( Zilles-1990 ). In the macaque it is identified with the equivalent areas of Vogts, area 1 of Brodmann (guenon) and area 2 of Brodmann (guenon) ( Powell-1959; Paxinos-2009a ). Defined cytoarchitecturally in the rat ( Swanson-2004 ) and the mouse ( Hof-2000 ) it is a wide horizontal strip on the dorsolateral aspect of the rostral two thirds of the cerebral cortex; it is bounded ventrally by the secondary somatosensory cortex and dorsomedially by the primary motor cortex. That area in rodents corresponds to area 3b in primates. Different authors subdivide the primary somatosensory area of rodents into six to nine subareas. All include the whisker sensory area, the nose sensory area, the mouth sensory area, the upper limb sensory area, the trunk sensory area and the lower limb sensory area, ( Swanson-2004, Paxinos-2009b ). In the Functional CNS Model - Rat the primary somatosensory area is classified as one of two somatosensory areas. The other is the secondary somatosensory cortex ( Swanson-2004 ).

Also known as: somatic area I, primary somesthetic area, primary somatic sensory area, primary somesthetic cortex, somatic sensory I, postcentral tactile area, somatic afferent area I, primary somatosensory cortex, primary somatosensory area, somatosensory strip, anterior parietal cortex, primary somatosensory areas, SI cortex

Models Where It Appears

Functional CNS Model - Rat

The Functional CNS Model - Rat (FMrat) ( Swanson-2004) is one of three hierarchical models representing the internal organization of the central nervous system (CNS). The others are the Structural CNS Model - Human (SThmn) and the Functional CNS Model - Human (FMhmn). The FMrat model represents the basic organization of the mouse ( Hof-2000 AMBA-2024 ) and, presumably, other rodents. Functional CNS models differ from structural models in that structures are defined and named by connectivity rather than by proximity to other structures at the same level. Functional models are more useful for representing longitudinal components of are grouped based on information drawn from multiple neuroscientific disciplines. such as connections, neurochemical characteristics, and role in physiogical and behavioral processes. While the Functional Model was developed primarily for an atlas of the rat brain ( Swanson-2004 ), the hierarchical organization of structures is for the most part applicable to the human, macaque, mouse and other mammalian brains as well. Structures at lower levels of the Functional CNS hierarchy are largely the same as in the Classical and Developmental Models, i.e., they were originally identified by stains for gray matter (Nissl substance) and white matter (myelin). At the next higher level they are grouped into basic connectional and functional systems of the CNS, such as the subcortical sensory systems, the brainstem motor system and the behavioral state system. At the highest levels CNS structures are grouped on the basis of dissection and embryologic precursors into cerebrum ( cerebral cortex and cerebral nuclei ), cerebellum, and cerebrospinal trunk.
