EEG desynchronization is a reliable correlate of excited neural structures of activated cortical areas. EEG synchronization within the alpha band may be an electrophysiological correlate of deactivated cortical areas. Such areas are not processing sensory information or motor output and can be considered to be in an idling state. One example of such an idling cortical area is the enhancement of mu rhythms in the primary hand area during visual processing or during foot movement. In both circumstances, the neurons in the hand area are not needed for visual processing or preparation for foot movement. As a result of this, an enhanced hand area mu rhythm can be observed.
脑电图去同步化是激活的皮质区域神经结构兴奋的可靠指标。α波段内的脑电图同步化可能是失活皮质区域的电生理指标。这些区域不处理感觉信息或运动输出，可被认为处于闲置状态。这种闲置皮质区域的一个例子是在视觉处理或足部运动期间，初级手部区域的μ节律增强。在这两种情况下，视觉处理或足部运动准备都不需要手部区域的神经元。因此，可以观察到手部区域μ节律增强。
