每天，需要使用反应选择过程整合和充分处理大量干扰感官输入。干扰效应通常使用经典范式进行研究，如Fanker和Simon任务。侧翼效应和西蒙效应的干扰源是不同的，根据双过程描述，在解决这些类型的干扰时涉及两个不同的功能通路。这些干扰源在多大程度上相互关联和相互作用，这是一个悬而未决的问题。我们在一项系统神经生理学研究中研究了这个问题，该研究采用了一种结合了侧翼效应样特征和西蒙效应样特征的混合范式。我们专注于事件相关的theta振荡，并使用波束成形方法来检查功能神经解剖网络。结果表明，Simon和Fleanker干扰通过调节theta带活动以非相加的方式相互作用，这可能反映了认知控制过程的招募。波束形成源重建显示，theta带活动与一个广泛的神经元网络有关，该网络包括前额叶和小脑区，包括MFG、SFG、IFG和SMA。这些区域与干扰处理和冲突解决有关，但不同干扰源的特异度不同。(C)2015 Elsevier Inc.保留所有权利。
Every day, a multitude of interfering sensory inputs needs to be integrated and adequately processed using response selection processes. Interference effects are typically investigated using classical paradigms like the Flanker and Simon task. The sources of interference for Flanker and Simon effect are known to be different and according to dual process accounts, two distinct functional pathways are involved in resolving these types of interference. It is an open question how far these sources of interference are related to each other and interact. We investigated this question in a system neurophysiological study utilizing a hybrid paradigm combining both Flanker effect-like and Simon effect-like features. We focus on event-related theta oscillations and use beamforming methods to examine functional neuroanatomical networks. The results show that Simon and Flanker interference interacted in a non-additive fashion by modulating theta band activity, probably reflecting the recruitment of cognitive control processes. Beamforming source reconstruction revealed that theta band activity was related to a broad neuronal network comprising prefrontal and cerebellar regions, including the MFG, SFG, IFG, and SMA. These regions were connected to interference processing and conflict resolution, but differed in the amount of specificity for different sources of interference. (C) 2015 Elsevier Inc.
