I feel uncertain that sleep is one of those things that do the nailing down，” Professor Stickgold said.Professor Stickgolds team trained the 24 people to tell the direction of three diagonal bars (斜线) shown for a sixtieth of a second on a computer screen full of horizontal stripes (水平线)Half the subjects were kept awake that night, while the others slept. Both groups were allowed to sleep for the second and third nights to make up for any differences in tiredness between the volunteers.Those who slept the first night were much better at remembering the task while the second group showed no improvement in spite of enjoying two nights of catch-up sleep.A further study by scientists at the Medical University at Lubeck in Germany showed that memories are laid down in two stages during the night. The first is during the deep, so-called “slow wave” sleep, which usually takes place in the first half of the night. The second, and less important stage happens during the periods of dreaming or “rapid eye movement (REM)”.

Man should have a good sleep if he wants to keep a good memory.D. Staying up la
