I experience this occasionally. The strongest occasion was approx 12 years ago. I was in the “High Country” NE Victoria, North of a town called Mansfield. I was out hunting Sambar Deer, 10 K’s from my off sider and in open bush land. About 1 Hr prior I came across droppings from wild dogs which were prevalent in the area and a real problem for farmers. I had this sensation all over my head and down my neck, it scared me. I had the feeling someone, something was watching me and was a bit shaken. I pulled myself together and continued my hunt. Never came across any deer or anything else that day.
According to Setz, this citation generally alludes to the effectiveness of the human voice and soft or whispered vocal sounds specifically as a trigger of ASMR for many of those who experience it, as demonstrated by the responsive comments posted to YouTube videos that depict someone speaking softly or whispering, typically directly to camera.
Some have called ASMR a "brain orgasm," but let's clear up one of the biggest misconceptions around this sensation: it's rarely sexual for anyone involved. While ASMR videos are often incredibly intimate, involve roleplaying aspects, and feature young, attractive women, the vast majority of their viewers (both male and female) enjoy them as a method of relaxation. In fact, the Swansea University study found that only 5% of participants reported using ASMR for sexual stimulation.
These reports have precipitated comparison between ASMR and synesthesia – a condition characterised by the excitation of one sensory modality by stimuli that normally exclusively stimulates another, as when the hearing of a specific sound induces the visualization of a distinct color, a type of synesthesia called chromesthesia. Thereby, people with other types of synesthesia report for example 'seeing sounds' in the case of auditory-visual synesthesia, or 'tasting words' in the case of lexical-gustatory synesthesia.
An article titled "An examination of the default mode network in individuals with autonomous sensory meridian response (ASMR)" by Stephen D. Smith, Beverley Katherine Fredborg, and Jennifer Kornelsen, looked at the default mode network (DMN) in individuals with ASMR. The study, which used functional magnetic resonance imaging (fMRI), concluded that there were significant differences in the DMN of individuals who have ASMR as compared to a control group without ASMR.
Payton is part of an ASMR wave that is attracting millions of viewers to videos that are intentionally designed to trigger the tingles. They feature people whispering into microphones, carving or crushing soap, and giving personal makeovers. In less than 10 years since the term was coined, oddly satisfying ASMR content has gone from a fringe concept on message boards to a global internet phenomenon.
The first study to perform actual brain imaging (fMRI) on subjects currently experiencing ASMR tingles (as opposed to individuals who were merely able to experience the phenomenon) was published in BioImpacts in September 2018. Subjects viewed several ASMR videos with a screen and headphones while inside the MRI scanner. The study found a significant difference in brain activation between time periods when the subject reported tingling (communicated by pressing a button), as compared to time periods when they were watching a video but not reporting tingling (communicated by pressing a different button, to control for brain activation effects caused by merely pressing a button). They concluded that "the brain regions found most active during the tingling sensations were the nucleus accumbens, mPFC, insula and secondary somatosensory cortex", and suggested that these were similar to "activation of brain regions previously observed during experiences like social bonding and musical frisson".
The term ASMR was coined in 2010 by Jennifer Allen, a 39-year-old penetration tester. “For years I thought, ‘Jeez, maybe I have a brain tumour or something,’” she recalls. From 1999 onwards, Allen searched steadfastly for others like her online. In the late noughties, she stumbled upon a SteadyHealth.com forum in which a user named okaywhatever51838 discussed a “weird sensation” that “feels good”.
ASMR is usually precipitated by stimuli referred to as 'triggers'. ASMR triggers, which are most commonly auditory and visual, may be encountered through the interpersonal interactions of daily life. Additionally, ASMR is often triggered by exposure to specific audio and video. Such media may be specially made with the specific purpose of triggering ASMR or originally created for other purposes and later discovered to be effective as a trigger of the experience.
