| | Noradrenaline & Pain |
 | | Noradrenaline (NA) is a key neurotransmitter of the endogenous pain inhibitory system. | | | A major caveat to this noradrenergic hypothesis of pain is that most experimental studies on which it is based use acute rather than chronic pain models and therefore do not mimic the major types of pain encountered in humans. | | | We are currently using several approaches to study the consequences of chronic noradrenaline depletion in nociceptive behavior: |
