One possible explanation of the findings, the research team suggests, is that the lateral prefrontal region is a ‘flexible hub’ that uses its connectivity to monitor and influence other brain regions. This happens in much the same way that the conductor of a symphony monitors and tweaks the real-time performance of an orchestra. The findings are based on an analysis of functional magnetic resonance fMRI brain images The findings are based on an analysis of functional magnetic resonance fMRI brain images captured as study participants rested passively and also when they were engaged in a series of mentally challenging tasks associated with fluid intelligence, such as indicating whether a currently displayed image was the same as one displayed three images ago. Previous findings relating lateral prefrontal cortex activity to challenging task performance were supported. Connectivity was then assessed while participants rested, and their performance on additional tests of fluid intelligence and cognitive control collected outside the brain scanner was associated with the estimated connectivity. Results indicate that levels of global brain connectivity with a part of the left lateral prefrontal cortex serve as a strong predictor of both fluid intelligence and cognitive control abilities. Although much remains to be learned about how these neural connections contribute to fluid intelligence, new models of brain function suggested by this research could have important implications for the future understanding — and perhaps augmentation — of human intelligence. The findings also may offer new avenues for understanding how breakdowns in global brain connectivity contribute to the profound cognitive control deficits seen in schizophrenia and other mental illnesses, Prof Cole suggests.
