Human intelligence is associated with adaptations of the brain to different cognitive demands: a new study shows that for brains of people with higher intelligence scores it is easier to adapt to different tasks.
Participants of the study (data from the Human Connectome Project with more than 800 adults) were either resting or had to complete various tasks. During this time, the activity of their brain was monitored using functional magnetic resonance imaging (fMRI). The amount of change in functional interactions of brain regions from one to another task were assessed and related to the intelligence scores of the participants. The results of the study suggest that the functional networks of humans with higher intelligence scores require less adjustment when switching between all different tasks – intelligence is a property of a widely distributed “multitask brain network”.
