Researchers say they’ve traced 32 of the most common genetic patterns at work in the human brain, as part of a mapping project that could lead to new insights about Alzheimer’s and other diseases.
“We’re really trying to understand the genetic basis for the architecture of the human brain,” said Ed Lein, a researcher at the Allen Institute for Brain Science and one of the authors of a study published online on Monday by Nature Neuroscience.
Lein told GeekWire that the study, based on data from the Allen Human Brain Atlas, demonstrates “we’re really much more similar than we are dissimilar” when it comes to the genetic code for our brain’s wiring. The genes that are most consistently associated with specific regions of the brain include some associated with Alzheimer’s, Parkinson’s and Huntington’s disease, as well as epilepsy and disorders associated with cocaine and nicotine use.
