Working memory capacity (WMC) is regarded as an index of individual attentional controllability. Tightly related to general intelligence, WMC varies across individuals. Studies have investigated underlying neural mechanism for individual differences in WMC, and found that the lateral part of the prefrontal cortex plays a critical role in it. Recent studies have attempted to identify more precise mechanism of the lateral prefrontal cortex that generates individual differences in WMC. The present talk covers the latest findings how the lateral prefrontal cortex contributes to the individual differences, with reviewing the neuroimaging studies. Those findings suggest that inter- and intra-connectivity of the lateral prefrontal cortex is the main source for individual differences in WMC. In other words, efficiency of those networks can be the determinant of individual WMC.
