Collectively , this electrical activity can be detected outside the scalp by an electroencephalogram ( eeg ) .
大脑的整体脑电活动可以在头皮外通过脑电图（eeg）探测出来。
Technically , what wilson did was come up with an interface combining an electroencephalogram , or brain wave monitor , with an on screen keyboard for selecting letters .
Eeg ( electroencephalogram ) readings , which test the brain 's electrical activity , were typical of an awake state and the rats moved about freely with their eyes open .
The researchers also wired their subjects up to an electroencephalogram ( which records brainwave patterns ) , and found a major decrease in abnormalities after 13 weeks on supplements .
When we 're awake , our neurons chatter in short , frequent bursts . Measured on an electroencephalogram ( eeg ) , these " alpha waves " look a lot like earthquake squiggles on a seismograph .
