People who are paralyzed from the neck down might soon be leading themselves around by the nose—literally. A new electric wheelchair allows the severely disabled to guide their movements by sniffing into tubes. Sniffing depends on highly coordinated motions of the back of the roof of the mouth, aka the soft palate. This region receives signals from several nerves that are often unaffected by paralytic injuries and disorders. That means some patients with disabilities. (source: news.nationalgeographic.com)
