介绍:
They found during the first night the left hemisphere of the brain was more active than the right hemisphere. This was during the first deep-sleep period, the researchers said.
Researchers did not keep measuring brain waves all night long. So, they don't know if the left hemisphere keeps "watch" all night. Or whether it "works in shifts" with the right hemisphere later in the night. 在第一个晚上他们发现大脑的左半球比右脑更加活跃。这是第一个深度睡眠期间,研究人员说。
研究人员没有保持测量脑电波一整夜。因此,他们不知道左半球持续整夜“手表”。还是“工作方式”,右脑在深夜。
hemisphere – n. either of the two halves of the brain
