Researchers at the Allen Institute for science in seattle have created a comprehensive atlas of the adult human brain that reveals the activity of the genes across the entire organ. The map was created from genetic analyses of about 900 specific parts of two “clinically unremarkable” brains donated by a 24 year old and 39 years old man, and half a brain from third man. They said the atlas would serve as a baseline against which they and others can compare the gegetic activity of disesed brains, and so shed ;ight on factors that underlie neurological and psychiatric conditions. This allow for the first time to overlay the human genome on to the human brain and gives essentially the Rosetta stone for understanding the link between the genome and the brain, and also gives a path forward to decoding how genetic disorder impact and produce brain diseases. The poer of the brain arises from its neutral wiring, its variety of cells and structures, and ultimately where and when different genes are switched on and off throughout the 1.9 kg lump of tissue.
