[4] Mori's activities expanded into other genres such as journalism and politics due to the popularity of his books, though his theory about human brains was pointed out to be pseudoscientific.
[18][19] Mori attained the degree of Doctor of Medicine, but did not become interested in researching the relationships between video games and human neuroscience until he met a programmer of computer software around 2000 when he made a new electroencephalograph.
[20] Additionally, the book was translated into traditional Chinese characters under the title Xiao Xin Dian Wan Nao!
[23] On October 19, 2004, the Computer Entertainment Supplier's Association announced that the neuroscientific works of Mori and Ryuta Kawashima about video games had insufficient evidence to claim something.
[25] In addition, Mori's book Genki na Nō no Tsukurikata: Ningen Rashisa o Hagukunde Suteki na Otona ni Narutameni (元気な脳のつくりかた―人間らしさを育んで、すてきな大人になるために, "The Way to Make the Healthy Brains: For Nurturing Humanities and Becoming Beautiful Adults"), published on August 1, 2006, was selected as the Japan National Council of Parent-Teacher Association's "recommended book" at that time.
[28] In 2008, Mori resigned from the head of the Japanese Society of Health and Behavior Sciences, being replaced by Shinji Murakami of Hokkaido University.
[29] On April 16, 2008, Senichi Club, a communication club comprising the readers of Sekai Nippō, the Japanese division of the World Times, invited Mori over a lecture meeting at Shibuya, in which Mori cited India as an advanced country of information technology.
