Kind: research · Impact: low

## In brief

- Scientists at the Broad Institute's Center for Human Brain Variation mapped previously hidden architecture and cellular makeup in the striatum.
- The striatum is involved in decision-making and movement and is affected in psychiatric disorders.
- The study reports distinct zones in the striatum and age-associated changes, with boundaries between zones blurring with age.

## Why it matters

The striatum is central to decision-making, movement and psychiatric conditions, so a finer map of its cellular zones and how they shift with age gives brain researchers a more detailed reference.
