A story on Frictionless Insight outlines a study published in science journal Cerebral Cortex relating the size of different areas in the brain to performance in video games. Word is: "Participants with a larger caudate nucleus and putamen outperformed others when forced to shift priorities and pursue changing goals within the same game. Participants with a larger nucleus accumbens (part of the brain's reward center) also outperformed others, probably due to the 'sense of achievement and the emotional reward' accompanying achievement in early learning." The study was funded by the Office of Naval Research and includes research from the University of Illinois, University of Pittsburgh, Massachusetts Institute of Technology and Florida State University. No word is included on where to cut your head open to measure your brain to see how it's impacting your gameplay.
