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.
Pretty cool… I actually teach something very similar in one of my addiction recovery books; Step 2 “The Next Level …” @ http://www.therealmofdouglas.com basically I show people how to call forth VERY strong emotions in my 5 Step Programming technique (belief modification technique A.K.A. self hypnosis), I can do it at will 24/7 with a very pronounced effect every time. One second at the drop of a dime every time. Interesting to see people experimenting with something very similar… I teach people about will power and how to become a functional personality type instead of an abusive personality type, while they quit using/abusing substances and learn a heck of a lot along the way. But yes in the time it takes to watch this video I could have created literally over 200 emotional responses covering my entire body head to toe with a very pronounced effect each time. It can best be described as a tingling sensation. I am however new to these ASMR videos, but yah very similar stuff. Great video.
Addressing the issue here of the wire scalp thingy… yeah that one’s right smack in the center of Sensual. Nothing sexual about it, though – for me – nothing particularly Spiritual either. I’ve only ever seen them sold as “Scalp Tinglers”, and didn’t find it very special. I much prefer my Denman scalp massagers. THOSE trigger intense ASMR’s for me. My whole body from crown to toes feels like it’s melting in joy when I scrub my head with two of those things, one in each hand. WOW.
If you don't like any of these, there are lots of other options. The top YouTube “ASMRtists,” like ASMR Darling and Gibi ASMR, have over a million subscribers and hundreds of videos each. You can also explore “unintentional ASMR:” content not created with tingles in mind, but that just so happens to promote them. (Painter Bob Ross has a cult ASMR following).
Allen verified in a 2016 interview that she purposely selected these terms because they were more objective, comfortable, and clinical than alternative terms for the sensation. Allen explained she selected the word meridian to replace the word orgasm due to its meaning of point or period of greatest prosperity.[clarification needed]
