ASMR

An illustration of the route of ASMR's tingling sensation

​

Autonomous sensory meridian response (ASMR), sometimes auto sensory meridian response, 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, it has been compared with auditory-tactile synesthesia and may overlap with frisson.

​

ASMR signifies the 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. A genre of videos intended to induce ASMR has emerged, over 13 million of which had been published on YouTube by June 2018
