Just do it. Okay. Now try to increase your alpha wave activity.

照做吧！好。试着增加你α波的活性。

A change from alpha wave drowsiness to lower frequency theta brain waves signify early sleep.

从α波睡意到较低频率的脑电波的变化表示早睡。

Your brain is relaxed, but still awake, a level of activity that EEGs measure as alpha waves.

你的大脑开始放松，但仍然是清醒的，EEG将这一阶段的活动测定为alpha波。

Some of you are awake but non attentive and your brain's giving you these large, regular alpha waves.

你们中的一些人是醒着的，但注意力不集中，并且您的大脑正在向您发出这些大的、规则的阿尔法波。

This exact moment is clearly evident on an EEG reading, as those alpha waves immediately transition to the irregular non-Rapid Eye Movement stage one (NREM-1) waves.

这一瞬间在脑电图上非常明显，alpha波立即转变为不规则的NREM-1波。

And in addition to that, there was this higher frequency piece, an alpha wave that appeared at the front of the head  at that loss of consciousness moment.

除此之外，还有一个更高频率的部分，即在失去意识的那一刻出现在头部前部的阿尔法波。

And experiments have shown that when a cell phone is transmitting, say during a phone call–the power of these alpha waves is significantly boosted, meaning phone transmissions can literally change the way your brain functions.

实验表明，当一部手机传输信号时，比如打电话，阿尔法脑波就会增强，这意味着手机信号传输确实可以改变大脑运作的方式。
