I didn’t even know this had a name! I have always been able to induce the feeling by focusing my attention on the base of my skull and letting the energy run. I have always enjoyed the feeling, but experience it as voluntary and not cultivated by sensory/cognitive experiences. Is this strange or are other folks eliciting this feeling when desired as well?
NBC News: "Why some researchers say 'brain tingles' could be the next big trend in relaxation" — "Have you ever felt a static-like or tingling sensation on the top of your head when someone brushes your hair or whispers to you? The feeling may travel down your arms and your spine, and it likely makes you feel very relaxed. Some call it a 'sparkly' feeling, and it might happen when you hear someone crinkle a piece of paper or when someone traces a word on your back.
The contemporary history of ASMR began on 19 October 2007 on a discussion forum for health-related subjects at a website called Steady Health. A 21-year-old registered user with the handle "okaywhatever" submitted a post describing having experienced a specific sensation since childhood, comparable to that stimulated by tracing fingers along the skin, yet often triggered by seemingly random and unrelated non-haptic events, such as "watching a puppet show" or "being read a story".
There are deeper meanings to "bliss". As more and more people mature, process their emotions and connect with others and their true purposes, "bliss" will happen between more and more people. Basically it's asexual, a bit pleasurable but more importantly it wakes up more areas of the brain/body-complex. People processing this need to activate their bodies more in other to balance the maturing mind/spirit-aspects of their being ("grounding"), and the physical activity may also help with backpains. The tendency of such people is to be a bit too seclusive, so need to remember to assert oneself more as well.
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.
In addition to the effectiveness of specific auditory stimuli, many subjects report that ASMR is triggered by the receipt of tender personal attention, often comprising combined physical touch and vocal expression, such as when having their hair cut, nails painted, ears cleaned, or back massaged, whilst the service provider speaks quietly to the recipient. Furthermore, many of those who have experienced ASMR during these and other comparable encounters with a service provider report that watching an "ASMRtist" simulate the provision of such personal attention, acting directly to the camera as if the viewer were the recipient of a simulated service, is sufficient to trigger it.
