Immersive virtual reality (VR) enables naturalistic neuroscientific studies while maintaining experimental control, but dynamic and interactive stimuli pose methodological challenges. We here probed the link between emotional arousal, a fundamental property of affective experience, and parieto-occipital alpha power under naturalistic stimulation: 37 young healthy adults completed an immersive VR experience, which included rollercoaster rides, while their EEG was recorded. They then continuously rated their subjective emotional arousal while viewing a replay of their experience. The association between emotional arousal and parieto-occipital alpha power was tested and confirmed by (1) decomposing the continuous EEG signal while maximizing the comodulation between alpha power and arousal ratings and by (2) decoding periods of high and low arousal with discriminative common spatial patterns and a Long Short-Term Memory recurrent neural network.

在沉浸式虚拟现实体验中解码来自 EEG 的主观情绪唤醒

沉浸式虚拟现实 (VR) 使自然神经科学研究成为可能，同时保持实验控制，但动态和交互式刺激带来了方法论上的挑战。我们在这里探讨了情绪唤醒（情感体验的基本特性）与自然刺激下的顶枕骨 alpha 功率之间的联系：37 名年轻健康的成年人完成了身临其境的 VR 体验，其中包括乘坐过山车，同时记录了他们的脑电图。然后，他们在观看他们经历的重播时不断评估他们的主观情绪唤醒。
