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.
Somatosensory Area 1, or S1, is for touch and proprioception in the somatosensory system. The somatosensory system feeds the Brodmann Areas 3, 1 and 2 of the primary somatosensory cortex.But there are also pathways for proprioception (via the cerebellum), and motor control (via Brodmann area 4).isual Area 1, or V1, is used for vision, via the visual system to the primary visual cortex. The sense of sight or vision enables us to see our external environment. It provides the richest and most detailed source of sensory information.
