  4. Shutting Off Pain • New lab experiments have shown it is possible to turn off pain sensitive neurons using an agent that acts as a photosensitive switch. • The chemical QAQ (ammonium-azobenzene-quaternary-ammonium) forms this switch to turn off pain. • Half of QAQ resembles one of the active parts of lidocaine which is a local anesthetic commonly used at the dentist.
