日有所思,夜有所梦,这是人们对做梦原因通常的理解。据新华社报道,最近,美国研究人员发现,做梦是大脑低级部分对高级部分的一种检测手段。 美国研究人员使用正电子释放断层扫描术对正在熟睡中的10名男性进行测量,以便精确地确定大脑的哪一部分晚间熟睡后还处于活跃状态。他们发现,大多数活跃的梦都发生在人睡着了而眼球还处于不断运动状态时,这时人的大脑里更加原始的部分正在活动中,就象大脑边缘系统那样能够调节情绪 Thoughtful day, night have a dream, this is people’s understanding of the usual reasons for the dream. According to the Xinhua News Agency, recently, American researchers found that dreaming is a test of the high-level part of the low-level part of the brain. US researchers used positron emission tomography to measure 10 sleeping asleep men and women to accurately determine which part of the brain is still active after a deep sleep at night. They found that most active dreams occur when people fall asleep while their eyeballs are constantly moving, as the more primitive part of the human brain is now functioning, just as the limbic system can regulate emotions
