Imagine being able to zoom into the brain to see various cells the way we zoom into Google maps of the world and can see houses on a street. And keep in mind that the brain is considered the most complex structure in the universe with 86 billion neurons. Zooming in is now possible thanks to a new brain atlas with unprecedented resolution. BigBrain is the first 3D microstructural model of the entire human brain, and is free and publicly available to researchers world-wide. The results of the BigBrain model, created at the Montreal Neurological Institute and Hospital – The Neuro, McGill University – in collaboration with researchers at Forschungszentrum Jülich, Germany, are published today in the June 20 issue of Science (http://www.sciencemag.org/content/340/6139/1472).
