1 | Scientists used a technique called electroencephalograhy (EEG) to analyse the drivers' brain signals. | |
2 | The team also measured brain activity while subjects napped using an electroencephalogram. | |
3 | The brain, too, sends out brain waves of electricity, which can be recorded in an electroencephalogram. | |
4 | Ultimately, the device will be designed so that you don' t even need to know about EEGs or how to set up electrodes. | |
5 | Most studies of physiology-based measurements of pain have focused on heart rate, skin conductance and EEG. |
