Using optogenetics activates CeAga neurons and turns off pain sensation.




Quote from article:  "Now the researchers are going to look for drugs that can activate only these cells to suppress pain as potential future pain killers, Wang said."


Question.  Another habit forming drug that some will abuse?  There is a fine line in pain.  Pain serves a purpose. Do we want it habitually turned off?
