Movie-watching is becoming a popular acquisition method to increase compliance and enable neuroimaging data collection in challenging populations such as children, with potential to facilitate studying the somatosensory system. However, relatively little is known about the possible crossmodal (audiovisual) influence of movies on cortical somatosensory processing. In this study, we examined the impact of dynamic audiovisual movies on concurrent cortical somatosensory processing using electroencephalography (EEG). Forty healthy young adults (18-25 years) received passive tactile fingertip stimulation while watching an "entertaining" movie and a novel "low-demand" movie called 'Inscapes' compared to eyes-open rest. Watching a movie did not modulate properties of early or late somatosensory-evoked potentials (SEPs). Similarly, no crossmodal influence on somatosensory adaptation, denoted by a reduction in SEP amplitude with repetitive tactile stimulation, was found. The prominent oscillatory responses in the alpha and beta frequency bands following tactile stimulation differed as a function of viewing condition, with stronger alpha/beta event-related desynchronization (ERD) during movie-watching compared to rest. These findings highlight that movie-watching is a valid acquisition method during which SEPs can be measured in basic research and clinical studies, but that the attentional demands of movies need to be taken into account when performing oscillatory analyses.

看电影对触觉刺激脑电图反应的影响

看电影正在成为一种流行的获取方法,以提高依从性并在具有挑战性的人群(如儿童)中收集神经影像数据,并有可能促进体感系统的研究。然而,关于电影对皮层体感处理可能产生的交叉模式(视听)影响的了解相对较少。在这项研究中,我们使用脑电图 (EEG) 检查了动态视听电影对并发皮层体感处理的影响。与睁眼休息相比,40 名健康的年轻人(18-25 岁)在观看“娱乐”电影和名为“Inscapes”的小说“低需求”电影时接受被动触觉指尖刺激。看电影不会调节早期或晚期体感诱发电位 (SEP) 的特性。同样,没有发现对体感适应的交叉模式影响,表现为重复触觉刺激时 SEP 幅度降低。触觉刺激后 alpha 和 beta 频带中的显着振荡响应因观看条件而异,与休息相比,观看电影期间的 alpha/beta 事件相关去同步 (ERD) 更强。这些发现强调,看电影是一种有效的获取方法,在此期间可以在基础研究和临床研究中测量 SEP,但在进行振荡分析时需要考虑电影的注意力需求。触觉刺激后 alpha 和 beta 频带中的显着振荡响应因观看条件而异,与休息相比,观看电影期间的 alpha/beta 事件相关去同步 (ERD) 更强。这些发现强调,看电影是一种有效的获取方法,在此期间可以在基础研究和临床研究中测量 SEP,但在进行振荡分析时需要考虑电影的注意力需求。触觉刺激后 alpha 和 beta 频带中的显着振荡响应因观看条件而异,与休息相比,观看电影期间的 alpha/beta 事件相关去同步 (ERD) 更强。这些发现强调,看电影是一种有效的获取方法,在此期间可以在基础研究和临床研究中测量 SEP,但在进行振荡分析时需要考虑电影的注意力需求。
