Brain scan study to understand workings of teenage mind

Researchers in Cambridge have begun a study to understand the teenage brain.

They have told BBC News that they will scan 300 people aged between 14 and 24 to see how their brains change as they grow older.

The £5m study aims to identify changes to the brain's wiring that controls impulsive and emotional behaviour as young people mature.

The investigation should also shed light on the emergence of mental disorders in young adults.

Ed Bullmore, professor of psychiatry at Cambridge University, explains how the study will work and what his team is looking for.
