[Remodeling of Neuronal Circuits in Chronic Pain].

Chronic pain is associated with various brain malfunctions, such as allodynia and anxiety. The underlying mechanism is a long-term alteration of neural circuits in the related brain regions. Here, we focus on the contribution of glial cells to build up pathological circuits. In addition, an attempt to enhance the neuronal plasticity of the pathological circuits to repair them to relieve abnormal pain will be introduced. The possible clinical applications will also be discussed.
