Alexey Pajitnov created Tetris on an Elektronika 60 while working for the Soviet Academy of Sciences at their Computer Center in Moscow with Dmitry Pavlovsky, and Vadim Gerasimov ported it to the IBM PC. Gerasimov reports that Pajitnov chose the name "Tetris" as a portmanteau of "tetromino tennis".
According to Richard Haier, prolonged Tetris activity can also lead to more efficient brain activity during play. When first playing Tetris, brain function and activity increases, along with greater cerebral energy consumption, measured by glucose metabolic rate. As Tetris players become more proficient, their brains show a reduced consumption of glucose, indicating more efficient brain activity for this task. The game can also cause a repetitive stress symptom in that the brain will involuntarily picture tetris combinations even when the player is not playing the game (the Tetris effect), although this can occur with any computer game showcasing repeated images or scenarios.
