Scientists have used brain scans to map the changes that occur in teenagers.
Dr Kirstie Whitaker is from the Department of Psychiatry at the University of Cambridge:
The research could help explain why the first signs of mental health problems emerge in adolescence, according to experts from the University of Cambridge.
Nearly 300 14-24 year-olds had MRI scans to study the structure of their brains.
By comparing the brains of teenagers of different ages, the researchers found that the outer regions of the brain shrink in size, becoming thinner.
As this happens, levels of myelin - the sheath that "insulates" nerve fibres, allowing them to communicate efficiently - increase within the outer regions.
Previously, myelin was thought mainly to reside in the "white matter," the tissue that connects areas of the brain, but this study shows that it can also be found in the outer regions and that levels increase during the teenage years.
"Adolescence can be a difficult transitional period and it's when we typically see the first signs of mental health disorders such as schizophrenia and depression.
"This study gives us a clue why this is the case: it's during these teenage years that those brain regions that have the strongest link to the schizophrenia risk genes are developing most rapidly."

A Cambridge councillor fears for people's safety, after a controversial decision to replace lampposts along a popular cycling route in the city centre.
The number of lights along Burrell's Walk has been cut, and the height, at six-metres tall, means the trees obstruct them.
"The idea was if they were so much taller, they would be able to light the path with fewer lights but because of the trees that are surrounding the lights. But because of the trees that are surrounding the lights actually the light levels simply aren't what they ought to be."
The council is defending its decision saying they needed replacing by more efficient ones.

Police have confirmed that thirteen men from Essex will appear in court in connection with an assault that left a football fan from Mildenhall with life changing injuries.
Cambridge United supporter Simon Dobbin travelled to Southend to see his team play in March 2015.
He was one of a small group of supporters who were attacked after the match as they walked to catch a train home.
The incident happened outside The Railway Pub in Southend, and left Simon with severe brain injuries.
After being treated in hospital for almost a year, Simon returned home to Mildenhall in March. His condition means he is unable to move or speak, and requires round the clock care.
As well as having the help of carers, Simon's wife Nicole and daughter Emily have the support of close family, most of whom live nearby.
Although Simon can't communicate verbally, Nicole believes he understands what has happened to him and is constantly frustrated by his condition.
Police today confirmed that thirteen men from Essex will face charges in connection with the incident last year.
One man has been charged with affray and a further 11 have been summoned to face the same charge at Southend Magistrates' Court on 2nd September.
A thirteenth man faces charges of assisting an offender and possession of a weapon.
Police are still appealing for anyone with information to come forward.

Bright red road markings have caused anger in Cambridge with residents living near Maltings Lane saying they're tantamount to "casual vandalism".
The signs have been painted on the roads as part of the city council's 20 mile per hour project. The council says setting the speed limit is a critical priority, but campaigners say the signs are "ludicrous".
" We new that the 20 limit was going to be introduced here and most people supported that, but we had no idea that it was going to result in signs like this. It's a complete eye-soar and it's happened throughout the whole area. This is complete overkill and a waste of money."

The company makes chips for smartphone brands such as Apple and Samsung and employs 3,000 people in Cambridge at the Science Park.
"ARM has been the proudest achievement in my life and so it's a very sad day for me personally and for technology in Britain."
