Video games are apparently better than their reputation. Neuropsychologists of the Ruhr-Universität Bochum let video gamers compete against non-gamers in a learning competition. During the test, the video gamers performed significantly better and showed an increased brain activity in the brain areas that are relevant for learning. Prof Dr Boris Suchan, Sabrina Schenk and Robert Lech report their findings in the journal Behavioural Brain Research.

Three years later Daniel Kreitman still chokes up when he talks about what he saw, and how it changed him. Kreitman, an upholsterer by trade, had taken psilocybin, a hallucinogen derived from mushrooms, in a trial at Johns Hopkins University School of Medicine for nicotine addiction.

So it’s a little strange how I’ve ended up now—someone who dances daily with triple integrals, Fourier transforms, and that crown jewel of mathematics, Euler’s equation. It’s hard to believe I’ve flipped from a virtually congenital math-phobe to a professor of engineering. One day, one of my students asked me how I did it—how I changed my brain.
