  2. Secondary somatosensory cortex - Wikipedia

    en.wikipedia.org/wiki/Secondary_somatosensory_cortex

    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 represented in the primary somatosensory cortex (S1) but also in a second region adjacent to S1. [1]

  3. Somatosensory system - Wikipedia

    en.wikipedia.org/wiki/Somatosensory_system

    Region S2 (secondary somatosensory cortex) divides into Area S2 and parietal ventral area. Area S2 is involved with specific touch perception and is thus integrally linked with the amygdala and hippocampus to encode and reinforce memories. Parietal ventral area is the somatosensory relay to the premotor cortex and somatosensory memory hub, BA5.

  5. Sensory cortex - Wikipedia

    en.wikipedia.org/wiki/Sensory_cortex

    The sensory cortex can refer sometimes to the primary somatosensory cortex, or it can be used as a term for the primary and secondary cortices of the different senses (two cortices each, on left and right hemisphere): the visual cortex on the occipital lobes, the auditory cortex on the temporal lobes, the primary olfactory cortex on the uncus of the piriform region of the temporal lobes, the ...

    Areas 3, 1 and 2 – Primary somatosensory cortex in the postcentral gyrus (frequently referred to as Areas 3, 1, 2 by convention) Area 4– Primary motor cortex; Area 5 – Superior parietal lobule; Area 6 – Premotor cortex and supplementary motor cortex (secondary motor cortex) (supplementary motor area) Area 7 – Visuo-motor coordination

  7. Somatotopic arrangement - Wikipedia

    en.wikipedia.org/wiki/Somatotopic_arrangement

    This cortex is typically represented as a sensory homunculus which orients the specific body parts and their respective locations upon the homunculus. Areas such as the appendages, digits, penis, [2] and face can draw their sensory locations upon the somatosensory cortex. The areas which are finely controlled (e.g., the digits) have larger ...

  8. Sensory nervous system - Wikipedia

    en.wikipedia.org/wiki/Sensory_nervous_system

    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 ...

  9. Brodmann area 5 - Wikipedia

    en.wikipedia.org/wiki/Brodmann_area_5

    Brodmann area 5 is a subdivision of the parietal cortex, part of the cortex in the human brain. BA5 is part of the superior parietal lobule and part of the postcentral gyrus. It is situated immediately posterior to the primary somatosensory cortex. [4]
