The investigators found that the brain's structure contains an almost perfect network of connections.
The researchers first created a map of a brain network that provided the best transfer of information between brain regions. They compared this "idealized" map with the brain's actual network and found that they were 89 percent similar.
The study was published recently in the journal Nature Communications.
Along with shedding new light on the brain's evolution, the findings could prove important in helping pinpoint the causes of brain diseases and developing treatments for them, according to Krioukov.
