"Researchers at the Mind Research Network today announced the findings of a scientific study that used brain imaging and Tetris to investigate whether practice makes the brain efficient because it increases gray matter.
"Over a three-month period, adolescent girls practiced Tetris, a computer game requiring a combination of cognitive skills. The girls who practiced showed greater brain efficiency, consistent with earlier studies. Compared to controls, the girls that practiced also had a thicker cortex, but not in the same brain areas where efficiency occurred.
"Relative to controls, red areas show where practice led to a thicker cortex; blue areas show more efficient brain function after practice; right image is right hemisphere; left image is the left hemisphere."Original article here: http://www.mrn.org/latest/brain-imaging-shows-playing-tetris-leads-to-both-brain-efficiency-and-thicker-cortex
