7.Anyone who has ever played the game of Tetris (俄罗斯方块) knows the game's surreal ability to spill into real life.After you shut off the game,you still see those Tetris blocks falling in your mind.You're grocery shopping and find yourself thinking about rearranging items on grocery shelves.Your mind continues to play the game,even when you're physically not.
Robert Stickgold,a Harvard professor,noticed something similar after a day hiking a mountain.That night,he dreamt he was still going through the motions of mountain hiking.Curious about this,he tried something:he got a group of college students of various skill levels to play Tetris and let them sleep in the Harvard sleep lab.
Over 60% of the students,including those who suffered from amnesia (键忘症),reported dreams of images of Tetris pieces falling,rotating (旋转),and fitting together.Interestingly,half the Tetris expert students reported such Tetris dreams,while 75% of the beginners did.
A study found that playing Tetris can grow your brain and make it more efficient.Adolescent girls played the game for an average of 1.5hours a week over three months.The cerebral cortex (大脑皮层) of the girls grew thicker,while brain activity in other areas decreased.Richard Haier,who had found that there was a"Tetris learning effect",in which the brain consumed less energy as mastery of the game rose,concluded,"The brain is learning which areas not to use."
Haier's study showed that as the girls practiced playing the game,nerve cells made connections,communicating through synapses (a synapse is a connection between two nerve cells).When you learn something,you change those connections.Every time you reactivate(激活) a circuit,synaptic efficiency increases,and connections become more durable and easier to reactivate.Stickgold says sleep plays a role in this memory process.
So to sum up,whenever you do specific tasks over and over again,they take up less of your brain power over time.And that's pretty amazing.
