However researchers at the moment are starting to grasp the position a group of nervous-system cells, referred to as glia, could play within the course of.

Initially considered easy connective tissues binding neurons collectively, glia have since been discovered to be instrumental in feeding neurons, cleansing their waste, and serving to them talk. Solely up to now 20 years have researchers begun to find how glia not solely reply to ache alerts and different neuronal exercise however usually manipulate it.

Because of this, the physique’s regular response to the acute ache that alerts an harm turns into an ongoing battle with a mysterious enemy.
