Clinical electroencephalography (EEG) and quantitative EEG (QEEG), despite their common underpinnings in electrophysiology and instrumentation, have quite different origins, histories, and priorities. This is exemplified by the fact that quite commonly, EEG practitioners do not use QEEG, and may not even be aware of it. A third field that interacts with EEG and QEEG is neurofeedback, in which signals derived from the EEG, principally QEEG metrics, are used as feedback information to facilitate learning and self-regulation in clients. This discipline also has its history and evolution, which is distinct from both EEG and QEEG. As a result, in the world of practitioners, these three worlds can be applied individually, in pairs, or together.

当世界碰撞

尽管临床脑电图（EEG）和定量脑电图（QEEG）在电生理学和仪器领域具有共同基础，但它们的起源，历史和优先领域却大不相同。事实证明，EEG从业人员通常不使用QEEG，甚至可能不知道它，这是一个事实。与EEG和QEEG交互的第三个领域是神经反馈，其中从EEG提取的信号（主要是QEEG指标）用作反馈信息，以促进客户的学习和自我调节。该学科也有其历史和发展，这与EEG和QEEG都不同。结果，在从业者的世界中，这三个世界可以单独，成对或一起应用。
