Scientists have demonstrated a new technique for detecting a painful nerve condition known as neuropathy, which affects millions of people with diabetes and many other patients as well. The painless technique focuses on tiny structures in the skin known as Meissner corpuscles, which encapsulate the endings of microscopic nerves in our hands, feet, and other areas. When someone tickles your feet, or lightly brushes the palm of your hand, or gives you a kiss — it’s Meissner corpuscles that are detecting the touch. The tiny structures act like little sensors, allowing us to feel light touch and pressure.
