London, - Scientists are appealing for more people to donate their brains for research after they die as they are lacking the brains of people with disorders such as depression and post-traumatic stress disorder, the BBC reported on Friday.
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.
In recent years, researchers have made links between the shape of the brain and mental and neurological disorders.
More than 3,000 brains are storied at the Harvard Brain Tissue Resource Center at McLean Hospital just outside Boston. It is one of the largest brain banks in the world.
Scientists at McLean Hospital and at brain banks across the world do not have enough specimens for the research community.
New treatments for many mental and neurological diseases are within the grasp of the research community, chief scientific officer at McLean hospital, Dr. Kerry Ressler told the BBC. However, he says it is the lack of brain tissue that is holding back their development.
"We have the tools and the ability to do some great deep-level biology of the human brain now, he said, adding that "What we are lacking are the tissues from those with the disorders we need to really understand." There is a shortage of brains from people with disorders that are incorrectly seen as psychological � rather than neurological in origin. These include depression and post-traumatic stress disorder.
