The changes of pain threshold affected by external environment

在本研究中，我们使用VAS(视觉模拟标尺)、Pain Vision(疼痛视觉)和fMRI(功能磁共振成像)来检测额外的感觉刺激在减弱完整人类对疼痛的感知方面的效果。当受试者听音乐时，VAS值降低，感觉或痛觉阈值增加。此外，听音乐时扣带回皮质的BOLD信号在fMRI上减弱。这些结果提示，音乐可能影响痛觉和痛觉阈值。

In the present study, we examined the effects of additional sensory stimulation in attenuating perception of pain in intact humans using VAS (visual analog scale), Pain Vision and fMRI (functional magnetic resonance imaging). When the subjects listened to music, the reduction in the VAS value and the increasing of sense perception or pain threshold are observed. Moreover, BOLD signal in the cingulated cortex during listening to music was attenuated on the fMRI. These results suggested that the music may affect pain perception and threshold.
