BRAIN IMAGING SHOWS PLAYING TETRIS LEADS TO BOTH BRAIN EFFICIENCY AND THICKER CORTEX
"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."
"We showed that practice on a challenging visuospatial task has an impact on the structure of the cortex, which is in keeping with a growing body of scientific evidence showing that the brain can change with stimulation and is in striking contrast with the pervasive and only-recently outmoded belief that our brain’s structure is fixed,” said Dr. Sherif Karama, a co-investigator at the Montreal Neurological Institute. This study, published in the open-access journal BMC Research Notes, is one of the first to investigate the effects of practice in the brain using two imaging techniques. The girls completed both structural and functional MRI scans before and after the three-month practice period, as did girls in the control group who did not play Tetris. A structural MRI was used to assess cortical thickness, and a functional MRI was used to assess efficient activity."
