The dorsal part of the human anterior cingulate cortex (dACC) is reliably activated in situations requiring cognitive control, especially during states of conflict. However, little is known about how individual differences in the neural characteristics of the dACC and major dimensions of behavior, affect this brain response. We recruited 28 healthy adults and employed a multi-modal neuroimaging approach combined with a task designed to specifically activate the human dACC and statistical path analysis to demonstrate clear roles for intelligence, personality and concentrations of neuronal N-acetylaspartate in determining dACC activation. These influences were comparable in magnitude to those associated with the experience of conflict. Our findings extend current understandings of the neural substrates of cognitive control by modeling the effect of neuronal viability, intelligence, and personality, on dACC activation. They also highlight the importance of considering enduring personal characteristics when mapping human brain-behavior relationships.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
