Making Sense of Touch You can feel your friend touch your shoulder because of your touch receptors. Image by Alex Proimos. You’re walking around your neighborhood and your friend sees you from across the street. As she catches up to you, you feel a tap on your right shoulder. You turn your head to look over that shoulder to see her smiling, excited to have run in to you. You can figure out which way to turn your head to see what’s going on behind you because the touch receptors in your skin are organized. Because of this you can tell if you were tapped on the right versus left shoulder.
