记忆提取的研究已经确定了脑电图（EEG）与测试项目的新旧状态，反应时间和记忆负荷的相关性。在目前的研究中，我们使用了多变量分析来解开这些相关变量的影响。在提取过程中，左顶叶θ波（4-8 Hz）振荡的功率与测试项目的记忆程度成比例增加，中央区域的θ波与决策有关。我们还研究了这些振荡动力学如何补充事件相关电位。这些发现首次证明了不同的θ振荡模式可以同时与行为的不同方面相关。(c)2006年爱思唯尔公司All rights reserved.
Studies of memory retrieval have identified electroencephalographic (EEG) correlates of a test item's old-new status, reaction time, and memory load. In the current study, we used a multivariate analysis to disentangle the effects of these correlated variables. During retrieval, power of left-parietal theta (4-8 Hz) oscillations increased in proportion to how well a test item was remembered, and theta in central regions correlated with decision making. We also studied how these oscillatory dynamics complemented event-related potentials. These findings are the first to demonstrate that distinct patterns of theta oscillations can simultaneously relate to different aspects of behavior. (c) 2006 Elsevier Inc. All rights reserved.
