在听觉刺激中，自己的名字是最强大的听觉刺激之一，它能够自动捕获注意力并引发强烈的电生理反应。被试自己的名字（SON）优先在右半球处理，主要是因为它的自我相关性和情感内容，以及其他与个人相关的信息，如熟悉的人的声音。情绪和自我相关的信息是否能够吸引注意力，并在未来被引入临床研究尚不清楚。在本研究中，我们使用脑电图并要求参与者数一个目标名字（主动条件）或只是听一个熟悉或不熟悉的声音发出的SON或其他不熟悉的名字（被动条件）。数据显示，与非目标名称相比，目标名称引发了强烈的与α事件相关的去同步，并引发了左偏侧的θ同步和δ同步。在被动条件下，在熟悉的声音和SON刺激下，在右半球观察到α去同步。总的来说，我们推测参与者在计算目标名字或听与个人相关的刺激时使用额外的注意力资源，这是由α去同步索引的，而左偏侧的θ同步可能与言语工作记忆负荷有关。在健康志愿者中验证了目前的方案后，建议进一步将该方案应用于意识障碍患者，其中残余认知加工和自我意识的程度仍然没有得到充分的了解。对基于名字的主动式被动任务的EEG进行时频分析。这些名字不是陌生的就是熟悉的。被计数的名字引起阿尔法去同步和左theta同步。自己的名字和熟悉的声音增强了强烈的右阿尔法去同步化。α去同步反应了注意力投入和情绪处理。
Among auditory stimuli, the own name is one of the most powerful and it is able to automatically capture attention and elicit a robust electrophysiological response. The subject’s own name (SON) is preferentially processed in the right hemisphere, mainly because of its self-relevance and emotional content, together with other personally relevant information such as the voice of a familiar person. Whether emotional and self-relevant information are able to attract attention and can be, in future, introduced in clinical studies remains unclear. In the present study we used EEG and asked participants to count a target name (active condition) or to just listen to the SON or other unfamiliar names uttered by a familiar or unfamiliar voice (passive condition). Data reveals that the target name elicits a strong alpha event related desynchronization with respect to non-target names and triggers in addition a left lateralized theta synchronization as well as delta synchronization. In the passive condition alpha desynchronization was observed for familiar voice and SON stimuli in the right hemisphere. Altogether we speculate that participants engage additional attentional resources when counting a target name or when listening to personally relevant stimuli which is indexed by alpha desynchronization whereas left lateralized theta synchronization may be related to verbal working memory load. After validating the present protocol in healthy volunteers it is suggested to move one step further and apply the protocol to patients with disorders of consciousness in which the degree of residual cognitive processing and self-awareness is still insufficiently understood. EEG during an active–passive task based on first names was time-frequency analyzed. The presented names were uttered either by an unfamiliar or a familiar voice. Counted names elicited alpha desynchronization and left theta synchronization. Own name and familiar voices enhanced strong right alpha desynchronization. Alpha desynchronization reflects attentional engagement and emotional processing.
