The error-related negativity (ERN) is an event-related potential occurring in the electroencephalogram (EEG) within 100 ms after the commission of an error. The ERN is thought to partially reflect emotionally aversive aspects of error commission, however, it has thus far not been related to the neural processing of other aversive events, such as brief aversive bodily sensations. Therefore, the present study investigated the links between the ERN and the N1 amplitudes of respiratory-related evoked potentials (RREP) and somatosensory evoked potentials (SEP). During the acquisition of high-density EEG, 41 healthy participants performed a Flanker task to evoke the ERN, while RREP and SEP were separately elicited, using inspiratory occlusions and electrocutaneous stimulation of the wrist. Significant positive correlations were observed between the amplitudes of the ERN and the N1 of RREP and SEP, suggesting relationships between the neural processing of different emotionally aversive events, namely errors and bodily sensations.
错误相关负波（ERN）是一种在脑电图（EEG）中出现的事件相关电位，发生在错误发生后的 100 毫秒内。ERN 被认为部分反映了错误发生时情感上令人厌恶的方面，然而，到目前为止，它还没有与其他令人厌恶的事件（如短暂的令人厌恶的身体感觉）的神经处理相关。因此，本研究调查了 ERN 与呼吸相关诱发电位（RREP）和体感诱发电位（SEP）的 N1 振幅之间的联系。在采集高密度脑电图期间，41 名健康参与者执行 Flanker 任务以诱发 ERN，同时分别使用吸气阻断和腕部电刺激诱发 RREP 和 SEP。ERN 的振幅与 RREP 和 SEP 的 N1 之间存在显著的正相关，表明不同情感厌恶事件（即错误和身体感觉）的神经处理之间存在关系。
