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.

I was diagnosed with IBS-D three years ago after a sudden onset diarrhea. The last year, I have been having pain under my right ribs just at the lower edge of the right rib cage, along the edge of ribs on the rights side. My pain is sometimes dull and sometimes stabbing. When making a sudden move like twisting towards back or if I bend sideways to the right, I sometimes get a stabbing pain unexpectedly. At times, it feels as if there is something under my ribs. Often my entire upper right quadrant is sore as if I had a bruise from something that hit me. Sometimes I can localize the pain at a specific spot, right at the edge of my right ribs sometimes it is more diffuse but still in the general area.
