Using optogenetics to manipulate the brains of opioid addicted mice, researchers discover a neural pathway that appears to be responsible for symptoms of withdrawal.
Inflammation caused by opioid use to both the brain and gut may exacerbate symptoms of negative emotions associated with withdrawal. Targeting the inflammation could help alleviate the negative experiences of opioid withdrawal and prevent dependence.
Opioid withdrawal cuts off the supply of serotonin to the nucleus accumbens, dramatically reducing sociability in mice and increasing social aversion.
