Neural mechanism underlying human cognitive ability

The researchers show that human intelligence is linked to interindividual differences in relational integration in hippocampal cognitive maps. 

Map-like representations of information learned piecemeal scaled with fluid intelligence, and this relationship specifically reflected relational integration rather than general mnemonic processing.

These findings highlight a neural mechanism underlying general cognitive ability.
