Emotion influences the perception of respiratory sensations, although the specific mechanism underlying this modulation is not yet clear. We examined the impact of viewing pleasant, neutral, and unpleasant affective pictures on the respiratory-related evoked potential (RREP) elicited by a short inspiratory occlusion in healthy volunteers. Reduced P3 amplitude of the RREP was found for respiratory probes presented when viewing pleasant or unpleasant series, when compared to those presented during the neutral series. Earlier RREP components, such as Nf, P1, N1, and P2, showed no modulation by emotion. The results suggest that emotion impacts the perception of respiratory sensations by reducing the attentional resources available for processing afferent respiratory sensory signals.
情绪会影响对呼吸感觉的感知，尽管这种调节的具体机制尚不清楚。我们研究了在健康志愿者中，观看愉快、中性和不愉快的情感图片对短吸气阻断诱发的呼吸相关诱发电位（RREP）的影响。与中性系列相比，当观看愉快或不愉快系列时，呼吸探针的 RREP 的 P3 振幅减小。RREP 的早期成分，如 Nf、P1、N1 和 P2，不受情绪的调节。结果表明，情绪通过减少用于处理传入呼吸感觉信号的注意力资源来影响对呼吸感觉的感知。
