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.
The primary somatosensory area in the human cortex is located in the postcentral gyrus of the parietal lobe. The postcentral gyrus is the location of the primary somatosensory area, the main sensory receptive area for the sense of touch.Like other sensory areas, there is a map of sensory space called a homunculus at this location. For the primary somatosensory cortex, this is called the sensory homunculus.Areas of this part of the human brain map to certain areas of the body, dependent on the amount or importance of somatosensory input from that area.he postcentral gyrus is the location of the primary somatosensory area, the main sensory receptive area for the sense of touch. Like other sensory areas, there is a map of sensory space called a homunculus at this location. For the primary somatosensory cortex, this is called the sensory homunculus.
