DONATE YOUR BRAIN

Scientists are appealing for more people to donate their brains for research after they die.
They say they are lacking the brains of people with disorders such as depression and post-traumatic stress disorder.
In part, this shortage results from a lack of awareness that such conditions are due to changes in brain wiring.
The researchers' aim is to develop new treatments for mental and neurological disorders.
The human brain is as beautiful as it is complex. Its wiring changes and grows as we do. The organ is a physical embodiment of our behaviour and who we are.
In recent years, researchers have made links between the shape of the brain and mental and neurological disorders.
