. ▁that ▁higher ▁intelligence ▁individuals ▁employ ▁more ▁efficient ▁whole - bra in ▁network ▁organization . ▁This ▁had ▁led ▁to ▁the ▁thought ▁that ▁cogn itive ▁control ▁capacity ▁may ▁be ▁supported ▁by ▁these ▁whole - bra in ▁network ▁properties . ▁The ▁ 2 0 1 2 ▁study ▁used ▁a ▁the or etic ▁approach ▁to ▁ne uro image ▁data ▁known ▁as ▁global ▁brain ▁connect ivity ▁( G BC ) ▁or ▁weight ed ▁degree ▁central ity . ▁G BC ▁let ▁the ▁research es ▁look ▁closely ▁at ▁specific ▁regions ▁and ▁their ▁range ▁of ▁connect ivity . ▁It ▁was ▁then ▁possible ▁to ▁examine ▁each ▁region ' s ▁role ▁in ▁human ▁cogn itive ▁control ▁and ▁intelligence . ▁The ▁study ▁used ▁f M RI ▁to ▁ac quire ▁data ▁and ▁examine ▁each ▁region ' s ▁connect ivity . ▁ ▁Eth ical ▁imp lications ▁ ▁Priv acy ▁and ▁confident ial ity ▁are ▁major ▁concerns ▁for ▁ne uro im aging ▁studies . ▁With ▁high - resol ution ▁an atom ical ▁images , ▁such ▁as ▁those ▁generated ▁by ▁f M RI , ▁it ▁is ▁possible ▁to ▁identify ▁individual ▁subjects , ▁putting ▁their ▁personal ▁/ ▁medical ▁priv acy ▁at ▁risk . ▁It ▁is ▁possible ▁to ▁create ▁surface ▁render ings ▁of ▁the ▁brain ▁and ▁face ▁from ▁a ▁vol um et ric ▁M RI , ▁which ▁can ▁be ▁pa ired ▁with ▁photograph s ▁to ▁identify ▁the ▁individual . ▁ ▁It ▁is ▁becoming ▁more ▁accepted ▁that ▁a ▁ne uro bi ological ▁basis ▁for ▁intelligence ▁exists ▁( at ▁least ▁for ▁reasoning ▁and ▁problem - sol ving ). ▁The ▁success ▁of
