(sciencedaily.com)—Krioukov and his colleagues discovered that the structure of the human brain has an almost ideal network of connections (magenta), enabling optimal transmission of information from one part of the brain to another.
The findings represent more than a confirmation of our evolutionary progress. They could have important implications for pinpointing the cause of neurological disorders and eventually developing therapies to treat them.
“An optimal network in the brain would have the smallest number of connections possible, to minimize cost, and at the same time it would have maximum navigability–that is, the most direct pathways for routing signals from any possible source to any possible destination,” says Krioukov. It’s a balance, he explains, raising and lowering his hands to indicate a scale. The study presents a new strategy to find the connections that achieve that balance or, as he puts it, “the sweet spot.”
