     Dreams may be more important than sleep. Some people don't need much sleep. But we all need to dream,

scientists say.

     Dreams take up about one quarter of our sleeping time. People have several dreams each night. Dreams are

like short films. They are usually in color. Some dreams are like old films. They come to us over and over again.

That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an

answer.

all day. These thoughts can carry over into dreams.

can disappear quickly from memory. Too much dreaming can be harmful. The more we sleep, the longer we

dream. The mind is hard at working when we dream. That is why we may have a long sleep and still wake up

tired.

回答下列有关神经系统的问题:

为了研究乙醇对人体神经行为能力的影响,科研人员选取若干自愿者,等量饮用同一种酒,参照世卫组织神经行为能力测试标准,测试简单反应时(对简单信号作出反应的最短时间)、视觉保留(对视觉信号记忆的准确数)和血液中乙醇浓度。以受试者自身未饮酒时为对照,计算能力指数相对值,结果如图所示。请回答下列问题:

随着血液中乙醇浓度的迅速升高,神经行为能力指数相对值明显降低,可以推测乙醇会()兴奋在相应反射弧上的传输时间,从而降低了机体的反应速度和判断能力。动物实验显示,乙醇能增加脑组织中某种抑制性神经递质与相应受体的结合。由此推测乙醇可能影响了兴奋在()处的传输。
