Introduction: The "autonomous sensory meridian response" (ASMR) is a neologism used to describe an internal sensation of deep relaxation and pleasant head tingling which is often stimulated by gentle sounds, light touch, and personal attention.Methods: An fMRI-based methodology was employed to examine the brain activation of subjects prescreened for ASMR-receptivity (n=10) as they watched ASMR videos and 12n/1200 wella identified specific moments of relaxation and tingling.Results: Subjects who experienced ASMR showed significant activation in regions associated with both reward (NAcc) and emotional arousal (dACC and Insula/IFG).Brain activation during ASMR showed similarities to patterns previously observed in musical old taylor whiskey 1933 price frisson as well as affiliative behaviors.

Conclusion: This is the first study to measure the activation of various brain regions during ASMR and these results may help to reveal the mechanistic underpinnings of this sensation.
