Just as fingerprints are unique, each human brain has a unique profile of signals between brain regions. These become more individual and specialised, particularly in adolescence.
Adolescence is also a time when most mental disorders emerge – though we still don’t know why some people develop mental illness and others don’t.
Looking for clues as to why, neurobiologist Daniel Hermens and his colleagues at the University of the Sunshine Coast have been tracking adolescent brain development using MRI scans for several years.
They found the extent of the uniqueness of an adolescent’s brain could help predict anxiety and depression symptoms that emerge later. Those with less unique brains had higher levels of distress down the line.
