Big Brain (big brain) is the name of the map of the human brain in 3D more detailed history. It has been created by scientists in Canada and Germany from 7,400 sheets of the brain of a woman of 65 years, according to a study published today in the journal Science .

The map has 50 times the resolution of previous models that mimicked traditional brain scanner and displays individual neurons and connections between them, at a level of microscopic detail. Also, the research is part of European Human Brain Project, which devotes 1,000 million euros to try to develop a computer model of the brain.

Its creators, researchers at the Heinrich Heine University in Dusseldorf (Germany) and at McGill University in Montreal (Canada), began the project in 2003. plan to make it available to the public for free through a web CBRAIN to be called in order to facilitate the work of researchers around the world.

The team chose the brain of a deceased donor 65 years because it had no clear signs of degenerative disease or other damage, the magazine explained study author, Katrin Amunts, who works in the University of Düsseldorf.

They preserved the brains with the chemical formaldehyde for several months, and then started slicing extremely fine , the thickness of a human hair, as they felt it to be more thick may lose details has indicated Amunts.

Then scanned each of the 7,400 lots of brain , which I took about 1,000 hours, according to the researcher.

Montreal study co-author, Alan Evans, was then in charge of rebuilding the brain in a coherent and correct errors and cracks generated during cutting, for what is supported in a computer network spread throughout Canada.

now want to create maps with the brain of a man and that of a younger person, in order to capture possible differences related to sex or development, according Science .

Simultaneously, U.S. scientists working on another map of the human brain designed to help cure diseases like Alzheimer’s or epilepsy , in an initiative announced in April by the president, Barack Obama, and has an initial investment of $ 100 million.
