Some ASMR video creators use binaural recording techniques to simulate the acoustics of a three-dimensional environment, reported to elicit in viewers and listeners the experience of being in close proximity to actor and vocalist.[33] Binaural recordings are usually made using two microphones, just like stereo recordings. However, in binaural recordings the two microphones tend to be more specially designed to mimic ears on humans. In many cases, microphones are separated the same distance as ears are on humans, and microphones are surrounded by ear-shaped cups to get similar reverb as human ears.
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".[29]
At the other end of the spectrum, I had a memory of a sexual experience that was such a strong trigger that for almost 15 years after the event, just thinking about that experience could trigger an actual orgasm with full body ASMR. (sorry if that’s TMI) (And don’t anyone be too jealous, I’m now old, gray, fat and long past those days in my life, but I’ve got the memories. LOL)
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 forum in which a user named okaywhatever51838 discussed a “weird sensation” that “feels good”.
Not everyone is fortunate enough to experience the tingling though. It’s like meditation — for some it works and for others it doesn’t, but the soft-spoken videos can help calm the anxious parts of the brain. Finding your own personal trigger could also help. Some common triggers are whispering, scratching and tapping, blowing, pages turning, concentration on a task, touching the head and Bob Ross.
I have been experiencing “ASMR” for as long as I can remember. Of course there are certain natural physical or visual triggers, but for me the trigger is a little more esoteric. It can happen at anytime and I generally connect to cognitive thought. I had no idea it had a name. When i am in meditation and i feel a connection with the divine (higher self, whatever anyone chooses to call it) it comes on as a full body buzz. I generally associate it with being aligned to something and getting a thumbs up, or green light to proceed. The absence of ASMR indicates a thumbs down for me, or a red light. So i guess you could say it is a tool of intuition for me. For example, i will have an ASMR top left quadrant of head, within a moment i will hear from someone i have been thinking about or not thinking about. In the beginning it would present only at the top of my crown, now it can originate at forehead or temporal lobes, base of head, etc. i had no idea it had a name until i stumbled on a you tube video and googled ASMR.bdoes anyone else associate it with something non-linear?

ASMR is usually precipitated by stimuli referred to as 'triggers'.[11] 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.[4]
