脑电图（EEG）允许研究人类的大脑-行为关系。我们对脑电图的大部分了解都是通过在控制良好的实验室条件下观察大脑与行为的关系。然而，通过将“正常”行为减少到最低限度，结果的生态有效性可能受到限制。最近发展到移动的EEG解决方案允许在实验室外的更自然的情况下研究大脑行为的关系。除了相对于运动的移动性和鲁棒性之外，移动的EEG系统还应该尽可能少地干扰参与者的行为。例如，当参与者明显戴着EEG帽时，与其他人的自然互动可能会受到阻碍。本研究评估了通过将小型化EEG电极集成到分立的棒球帽和个性化耳机中来实现EEG监测的非侵入性解决方案所获得的信号质量。我们表明，这种微型电极位于头皮和耳朵的位置可以可靠地记录事件相关电位在P300脑机接口应用。
Electroencephalography (EEG) allows the study of the brain–behavior relationship in humans. Most of what we have learned with EEG was through observing the brain–behavior relationship under well-controlled laboratory conditions. However, by reducing “normal” behavior to a minimum the ecological validity of the results can be limited. Recent developments toward mobile EEG solutions allow to study the brain–behavior relationship outside the laboratory in more natural situations. Besides mobility and robustness with respect to motion, mobile EEG systems should also interfere as little as possible with the participant's behavior. For example, natural interaction with other people could be hindered when it is obvious that a participant wears an EEG cap. This study evaluates the signal quality obtained with an unobtrusive solution for EEG monitoring through the integration of miniaturized EEG ton-electrodes into both a discreet baseball cap and an individualized ear piece. We show that such mini electrodes located at scalp and ear locations can reliably record event related potentials in a P300 brain–computer–interface application.
