ASMR seems to need an emotional component to it, and Winter says that’s not accidental. “Some things may remind you of your mother or being a kid,” he says. “I’d guess that it’s no accident that a lot of the videos of someone whispering feature an attractive woman, which make you think of your mom whispering to you when you went to sleep.” Those memories the videos evoke are likely comforting, and can shift people into a more relaxed state that then helps them fall asleep, he says.
But creating an ASMR video isn't as simple as filming for an hour. Maria said her more complex videos take about three days to create. She'll write up a script with specific soothing words she should be using and do research into what sounds she should incorporate. She tests out the appropriate lighting and sound levels before filming. She sets up microphones positioned where a viewer's ears would be in real life, and places the lens where a onlooker's eyes would be. Then, after filming the video, she goes into post-production, which includes a special ear toward sound to remove any clap or loud noise.
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".
It’s not really a physical feeling if that makes sense, but there is a powerful reaction to the sounds nonetheless, to the point where I’m instinctively arching my neck, and a feeling does wash over you that is truly unique, almost addictive. What I don’t fully understand is why my mind chose just now to react when I haven’t had anything close to an ASMR experience before. I’d say that I’ve just found the right trigger, but I’m even reacting to videos that did nothing for me in the past. Like something clicked in my head recently.
The story follows Tom More, a psychiatrist living in a dystopian future who develops a device called the Ontological Lapsometer that, when traced across the scalp of a patient, detects the neurochemical correlation to a range of disturbances. In the course of the novel, More admits that the 'mere application of his device' to a patient's body 'results in the partial relief of his symptoms'.
