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.
Previous chapters described the ways in which the different somatosensory receptors respond to specific types of somatosensory stimuli and that the receptors, by virtue of their selective sensitivities, extract specific information about the somatosensory stimulus.he somatosensory association cortex is located in the superior parietal lobe (a.k.a. posterior parietal cortex), which is posterior to SI. The highest degree of convergence of somatosensory information occurs in the posterior parietal cortex.
