自主感觉经络反应(ASMR)是一种感知状态，在这种状态下，特定的视觉和听觉刺激持续地在头皮和颈部引发刺痛感，有时会扩散到背部和四肢。这些触发刺激通常是社交的，几乎是亲密的，本质上(例如，听到窃窃私语，或看着某人梳头)，通常会引发一种平静和积极的情绪状态。令人惊讶的是，尽管ASMR在普通人群中普遍存在，但还没有发表的研究检查ASMR的神经基础。在目前的研究中，11名ASMR患者和11名匹配的对照组的默认模式网络(DMN)进行了对比。结果表明，ASMR患者的DMN功能连接性明显低于对照组。ASMR患者的DMN也显示枕叶、额叶和颞叶皮质区域之间的连通性增加，这表明ASMR与多种静息状态网络的混合有关。这种非典型的功能连接可能会影响与ASMR相关的独特的感觉-情感体验。
Autonomous Sensory Meridian Response (ASMR) is a perceptual condition in which specific visual and auditory stimuli consistently trigger tingling sensations on the scalp and neck, sometimes spreading to the back and limbs. These triggering stimuli are often social, almost intimate, in nature (e.g., hearing whispering, or watching someone brush her hair), and often elicit a calm and positive emotional state. Surprisingly, despite its prevalence in the general population, no published study has examined the neural underpinnings of ASMR. In the current study, the default mode network (DMN) of 11 individuals with ASMR was contrasted to that of 11 matched controls. The results indicated that the DMN of individuals with ASMR showed significantly less functional connectivity than that of controls. The DMN of individuals with ASMR also demonstrated increased connectivity between regions in the occipital, frontal, and temporal cortices, suggesting that ASMR was associated with a blending of multiple resting-state networks. This atypical functional connectivity likely influences the unique sensory-emotional experiences associated with ASMR.
