The intelligent brain in conflict

Trends Cogn Sci. 2003 Sep;7(9):375-377. doi: 10.1016/s1364-6613(03)00193-1.

Abstract

Can individual differences in general reasoning ability be reduced to an elementary cognitive process or isolated to a neural circuit? A breakthrough neuroimaging study finds that fluid intelligence and attention control are behaviorally linked via the neural activity in brain areas involved in resolving cognitive conflict.
