Story summary

A groundbreaking study from the Shenzhen Institutes of Advanced Technology uncovers a striking link between social rank and addiction in male rodents. Low-ranking mice exhibited heightened drug-seeking behavior, driven by changes in dopamine pathways. Remarkably, boosting the mesocortical pathway not only curbed this behavior but also elevated their social status, hinting at new avenues for addiction therapies. In contrast, female mice showed no variation in drug-seeking based on rank.
