为了更好地了解可能的功能意义的电生理感觉门控措施，反应抑制的中潜伏期听觉事件相关电位（ERP）组件进行了比较，失配负波（MMN）和刺激过滤和被动注意转换现象的自评指数在年龄限制的健康成年人样本。在成对点击范例期间测量的PI感觉门控与在声学oddball范例（强度偏差）期间测量的MMN振幅相关。此外，表现出不太强大的PI抑制的个人赞同较高的“感知调制”的困难率，而组件N1抑制更密切相关的“过度包含”的不相关的声音到注意力的焦点。这些研究结果表明，ERP组件的调查是不是多余的，但对应于不同的可能相关的前吸引力处理系统。
To better understand the possible functional significance of electrophysiological sensory gating measures, response suppression of midlatency auditory event related potential (ERP) components was compared to the mismatch negativity (MMN) and to self-rated indices of stimulus filtering and passive attention-switching phenomena in an age-restricted sample of healthy adults. P I sensory gating, measured during a paired-click paradigm, was correlated with MMN amplitude, measured during an acoustic oddball paradigm (intensity deviation). Also, individuals that exhibited less robust P I suppression endorsed higher rates of "perceptual modulation" difficulties, whereas component N1 Suppression was more closely related to "over-inclusion" of irrelevant sounds into the focus of attention. These findings suggest that the ERP components investigated are not redundant, but correspond to distinct-possibly related-pre-attractive processing systems.
