A healthy brain is critical to a person’s cognitive abilities, but measuring brain health can be a complicated endeavor. A new study by University of Illinois researchers reports that healthy brain metabolism corresponds with fluid intelligence – a measure of one’s ability to solve unusual or complex problems – in young adults.

“Fluid intelligence is one of the most useful cognitive measures available,” said U. of I. Ph.D. candidate Aki Nikolaidis. “This domain relates to an individual’s job satisfaction and salary level, among other real-world outcomes,” he said...
