Four months after Novella's blog post, Tom Stafford, a lecturer in psychology and cognitive sciences at the University of Sheffield, was reported to have said that ASMR "might well be a real thing, but it's inherently difficult to research...something like this that you can't see or feel" and "doesn't happen for everyone". Stafford compared the current status of ASMR with development of attitudes toward synesthesia, which he said "for years...was a myth, then in the 1990s people came up with a reliable way of measuring it".[41]
While little scientific research has been conducted into potential neurobiological correlates to the perceptual phenomenon known as 'autonomous sensory meridian response' (ASMR), with a consequent dearth of data with which to either explain or refute its physical nature, there is voluminous anecdotal literature comprising personal commentary and intimate disclosure of subjective experiences distributed across forums, blogs, and YouTube comments by hundreds of thousands of people. Within this literature, in addition to the original consensus that ASMR is euphoric but non-sexual in nature, a further point of continued majority agreement within the community of those who experience it is that they fall into two broad categories of subjects.
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?
Think about nails scratching a chalkboard for one second. Are you flinching? One study found that this sound literally accelerated the participants’ stress levels, quickening heart rates, heightening blood pressure and even altering the skin’s electrical conductivity. In the study, the scientists discovered that—when stimulated with this screeching sound, the auditory cortex interacted with the amygdala, which controls responses related to fear and emotions.
While many colloquial and formal terms used and proposed between 2007 and 2010 included reference to orgasm, there was during that time a significant majority objection to its use among those active in online discussions, many of whom have continued to persist in differentiating the euphoric and relaxing nature of ASMR from sexual arousal.[citation needed] However, by 2015, a division had occurred within the ASMR community over the subject of sexual arousal, with some creating videos categorized as ASMRotica (ASMR erotica), which are deliberately designed to be sexually stimulating.[8][9]
