## TL;DR

New research suggests that serotonin's role in mental health is more complicated than previously believed.

## Contribution

The paper challenges the traditional view of serotonin as the sole cause of mental health conditions.

- The relationship between serotonin and mental health is more nuanced than previously thought.
