Autonomous sensory meridian response (ASMR) is a perceptual phenomenon characterized by pleasurable tingling sensations in the head and neck, as well as pleasurable feelings of relaxation, that reliably arise while attending to a specific triggering stimulus (e.g., whispering or tapping sounds). Currently, little is known about the neutral substrates underlying these experiences. In this study, 14 participants who experience ASMR, along with 14 control participants, were presented with four video stimuli and four auditory stimuli. Half of these stimuli were designed to elicit ASMR and half were non-ASMR control stimuli. Brain activity was measured using a 32-channel EEG system. The results indicated that ASMR stimuli—particularly auditory stimuli—elicited increased alpha wave activity in participants with self-reported ASMR, but not in matched control participants. Similar increases were also observed in frequency bands associated with movement (gamma waves and sensorimotor rhythm). These results are consistent with the reported phenomenology of ASMR, which involves both attentional and sensorimotor characteristics.

自主感觉经络反应 (ASMR) 是一种知觉现象，其特征在于头部和颈部令人愉悦的刺痛感，以及愉悦的放松感，当注意特定的触发刺激（例如，耳语或敲击声）时确实会出现这种感觉。目前，人们对这些体验背后的中性底物知之甚少。在这项研究中，14 名经历过 ASMR 的参与者以及 14 名对照参与者接受了四个视频刺激和四个听觉刺激。这些刺激中有一半旨在引发 ASMR，一半是非 ASMR 控制刺激。使用 32 通道 EEG 系统测量大脑活动。结果表明，ASMR 刺激——尤其是听觉刺激——引起了自我报告的 ASMR 参与者的 α 波活动增加，但不是在匹配的控制参与者中。在与运动相关的频带（伽马波和感觉运动节律）中也观察到了类似的增加。这些结果与所报道的 ASMR 现象学一致，后者涉及注意力和感觉运动特征。
