The researchers liken the favored networks to a country club setting, in which people with a great number of social connections bond with other connection-rich socialites. In the brain, the socialites (the hubs with the most connections, shown in red in the image) included the regions that aggregate and process many kinds of information—the superior frontal and superior parietal cortex, for example, as well as the subcortical hippocampus, putamen and thalamus.
