Game brain

[1] Mori, a professor in the Humanities and Sciences division of Nihon University in Japan, originally coined the term and presented the concept in his 2002 book The Terror of Game Brain (ゲーム脳の恐怖, Gēmu Nō no Kyōfu).

Mori claims his study has revealed that people who spend long periods playing video games have less activity in the brain's pre-frontal region, which governs emotion and creativity, in contrast to their peers.

[2] Specifically, Mori asserts that side effects can include loss of concentration, an inability to control temper and problems socializing or associating with others.

[4] Mori's theory was criticized as unwarranted research by established neuroscientists and brain specialists, because he used unreliable measures and misinterpreted the fluctuation of beta waves.

Professor Akira Baba of the graduate school of the University of Tokyo pointed out that even shogi player Yoshiharu Habu probably has Game Brain under his theory.
