For years, serotonin has been linked to anxiety, but new research flips the script—higher serotonin in the cerebellum might actually reduce anxiety, not increase it.
By manipulating serotonin-releasing neurons, scientists found they could dial anxiety levels up or down in mice. This discovery challenges existing theories and could lead to more precise anxiety treatments in the future.
Unlocking the Neural Circuitry of Anxiety
Understanding how brain circuits regulate anxiety could help scientists develop more precise treatments. Previous research has separately linked serotonin levels and the cerebellum to…
