Kind: research · Impact: medium

## In brief

- A Cell study reports that dopamine reinforces specific actions within juvenile social play on a sub-second timescale.
- In a Shank3-deficient autism model, disrupted dopamine reinforcement is linked to social deficits.
- Correcting the reinforcement signal in real time restored normal play, according to the source.

## Why it matters

The work links moment-to-moment dopamine signalling to a concrete social behaviour and to an autism-model deficit, offering a mechanistic target for future research on social function.
