　　50、【睡觉多打字快】

　　V1 RM(rapid eyemovement) sleep VS non-RM sleep有眼动睡眠和无眼动睡眠对思维能力的影响：A study was done involving an experimental and a controlgroup to have them learn to navigate a 3D maze. The blood flow in theparahippocampas gyrus increased in conjunction with the individual&apossperformance through the 3D maze. Participants were then trained in the maze for4 hours and later, during the various sleep cycles of nonREM sleep, REM sleepand wakulness, they were scanned twelve times using PET during the night. ThePET scan demonstrated a higher blood flow in the hippocampus during SWS/non-REMsleep due to the training from the previous day while the control groupexhibited no increased blood flow and they had not received the training theprior day. The brain activity during sleep, according to this study, would showthe events of the previous day does make a difference. One theory suggests amodel of Hippocampal-neocortical dialogue. "Two stages of hippocampalactivity have been proposed, the first being the recording of the memory duringwaking and the second involving the playback of the memory during nonREM sleep.This process of reactivation of memory firing sequences is believed togradually reinforce initially weak connections between neocortical sitesallowing the original information to be activated in the cortex independentlyof the hippocampus, and thus ensuring rreshed encoding capacity of thehippocampus." Maquet concluded that the areas of the brain involved withinformation processing and memory have increased brain activity during the slowwave sleep period. Events experienced in the previous day have more ficientand clearer memory recall the next day thus indicating that the memory regionsof the brain are activated during SWS/non-REM sleep instead of being dormant aspreviously thought.

　　题中的实验改为：两组人比赛打字，昨晚睡了觉的，打字快，正确率高。问支持。
