An autonomous sensory meridian response (ASMR)[2][3][4] is a tingling sensation that usually begins on the scalp and moves down the back of the neck and upper spine. A pleasant form of paresthesia,[5] it has been compared with auditory-tactile synesthesia[6][7] and may overlap with frisson.[8] ASMR is a subjective experience of "low-grade euphoria" characterized by "a combination of positive feelings and a distinct static-like tingling sensation on the skin". It is most commonly triggered by specific auditory or visual stimuli, and less commonly by intentional attention control.[1][9]
