Champaign-- The size of a region in the cerebral cortex influences a person's motor skills and ability to adapt to changing environments, scientists in Illinois said.
Researchers at the University of Illinois, Urbana-Champaign, used video games to test how healthy adults learned and performed quickly changing tasks. The participants' brains were analyzed with high-resolution magnetic resonance imaging.
The results showed nearly 25 percent of the variability in achievement could be predicted by measuring the volume of three areas of the brain: the caudate nucleus and the putamen in the dorsal striatum and the nucleus accumbens in the ventral striatum.
