Uncovering the Brain's Pathways Hijacked by Addiction

Researchers have discovered how drugs like cocaine and morphine manipulate the brain's natural reward system, leading to compulsive drug-seeking behaviors. By tracking neurons in the nucleus accumbens, the study found that drugs disrupt the same brain cells responsible for processing natural rewards, offering potential targets for new addiction treatments. The research also identified the mTORC1 signaling pathway and the Rheb gene as potential therapeutic targets, shedding new light on the neural underpinnings of drug addiction.
