| Research Abstract |
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.
