Aspetti neurobiologici del’inteligenza generale: l’architettura del fattore g

The development of advanced neuroimaging methods led to the localization of allowed us to localize the cortical areas that are involved with the execution of complex cognitive tasks. Previous studies have shown that higher intelligence was not associated with brain size, but rather it reflected the integrity of the network linking those cortical areas. In addition, they showed that individual differences in intelligence corresponded to differential pattern of cortical activation and that, despite similar levels of intelligence, males and females might differ in terms of brain activity. In the future, longitudinal investigations on normal aging as well as on neurological populations might provide new promising insight on the neurobiology of intelligence.
