The nutrients that food gives you, from vitamins to proteins, have specific functions in the body that keep you healthy and support your body's systems. But your body cannot use the nutrients you eat until it breaks them down in small pieces to then absorb them.
The primary somatosensory cortex is a region of the brain where nerve signals from the sense of touch are normally received.It is generally located in a part of the brain called the parietal lobe, in a structure called the post central gyrus.f this area is damaged, a person can touch something, feel it, but not be able to figure out what it is. Scientists first mapped the primary somatosensory cortex in the 1950s. During brain surgery, surgeons could stimulate parts of the brain and see where a patient felt something.
Primary somatosensory cortex (SI; areas 3,1,2) is located in the post central gyrus. This receives somatotopic input from the VPL and VPM of the thalamus. Histologically, this area would consist of granular cortex.ssociation and Commissural Fibers. Finally, regions of the cerebral cortex are tied together by bundles of white matter fibers. There are association bundles that connect one part of the cortex to another. These association fibers typically arise from layer III and terminate in layers I and II.
