文摘

We investigate intelligence-related differences in brain network organization. Graph analysis was used to study the intrinsic functional connectivity of the brain. Intelligence (IQ) was not related to global efficiency of network organization. High IQ was associated with high nodal efficiency in the brain's salience network. High IQ was associated with low nodal efficiency of the temporo-parietal junction.
