Autonomous Sensory Meridian Response

ASMR 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 is a subjective experience 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.
