Previous studies exploring mental time travel paradigms with functional neuroimaging techniques have uncovered both common and distinct neural correlates of re-experiencing past events or pre-experiencing future events. A gap in the mental time travel literature exists, as paradigms have not explored the affective component of re-experiencing past episodic events; this study explored this sparsely researched area. The present study employed standardized low resolution electromagnetic tomography (sLORETA) to identify electrophysiological correlates of re-experience affect-laden and non-affective past events, as well as pre-experiencing a future anticipated event. Our results confirm previous research and are also novel in that we illustrate common and distinct electrophysiological correlates of re-experiencing affective episodic events. Furthermore, research from this experiment yields results outlining a pattern of activation in the frontal and temporal regions is correlated with the time frame of past or future events subjects imagined.
先前运用功能神经影像学技术探索心理时间旅行范式的研究揭示了再体验过去事件或预体验未来事件的共同和独特的神经关联。心理时间旅行文献中存在一个空白,因为这些范式尚未探索再体验过去情景事件的情感成分;本研究探索了这个研究较少的领域。本研究采用标准化低分辨率电磁断层成像(sLORETA)来识别再体验带有情感和非情感的过去事件以及预体验未来预期事件的电生理学关联。我们的研究结果证实了先前的研究,并且也是新颖的,因为我们说明了再体验情感情景事件的共同和独特的电生理学关联。此外,这项实验的研究结果概述了一个模式,即激活额区和颞区与被试想象的过去或未来事件的时间框架相关。
