@...@**These highly active rats would run on their wheels constantly,** Ruegsegger said// **However, when we chemically activated their mu~opioid receptors, those rats drastically reduced their amounts of activity//© Since exercise and addiction to substances follow this same chemical process in the brain, it stands to reason that activating these receptors in people with dangerous addictions could provide the same rewards they are craving without the use of dangerous drugs or alcohol//**
@...@When MU researchers studied the brains of the rats, they found 400 percent more of the reward receptors in the extremely active rats than the extremely lazy rats// ©They believe this indicates that the extremely active rats were active to receive **rewards** from their mu~opioid receptors, which may explain why they voluntarily run such extreme amounts//
