Imaging subjects' brains with fMRI as they reported experiencing ASMR tingles suggests support for this hypothesis, because brain areas such as the medial prefrontal cortex (associated with social behaviors including grooming), and the secondary somatosensory cortex (associated with sensation of touch) were activated more strongly during tingle periods than control periods.
You have no idea how happy I was when I found out what ASMR was. I have had the trigger since I was a child and just like this says, I never understood what it was but I liked it. But sometimes bothering me. Like, if I need to focus in school while a teacher is trying to help me, but the sound of them flipping the pages in a book makes me sleepy and lose focus. And when I haven’t had enough sleep I seem to get the trigger from almost everything…
“The strongest type of tingle…feels like sparkles or little fireworks going off,” she says. “The strongest one would give you the feeling of being exhausted, pleasantly tired, satisfied almost you want to say. Then there are much less strong tingles, and they feel just pleasant. Almost like sand is being poured down your spine. [Or] like when you get the funny elbow, when you hit it and it feels like it just goes off everywhere.”

In the current study, the default mode network (DMN) of 11 individuals with ASMR was contrasted to that of 11 matched controls.
Last year, Rooster Teeth released the documentary "The World's Greatest Head Massage: An ASMR Journey," where filmmakers traveled to Pushkar, India to find Baba the Cosmic Barber. Unbeknownst to Baba, he had become a YouTube sensation after people had been uploading videos of his "cosmic energy" shaves and head massage techniques. Baba has since created his own YouTube channel, ASMR Barber, to take advantage of his popularity.
Most importantly for Hunnicutt, Aoki seems to love making videos. Like most five-year-olds, she loves trying on her mother’s lipsticks, but unlike most five-year-olds, Aoki was encouraged to rummage in her mum’s make-up bag – and a camera captured the results. “I put all the lipstick on!” Aoki grins, explaining this video was her favourite to make.
Many of those who experience ASMR report that some specific non-vocal ambient noises are also effective triggers of ASMR, including those like the sound of rain, fingers scratching or tapping a surface, the crushing of eggshells, the crinkling and crumpling of a flexible material such as paper, or writing. Many YouTube videos that are intended to trigger ASMR responses capture a single person performing these actions and the sounds that result.
