A smaller, more recent study offers a hint as to where ASMR research might go. Last year, psychology professor Stephen Smith and two colleagues at the University of Winnipeg put 22 subjects into fMRI scanners. Half were people who reported experiencing ASMR, and half were controls. Because the researchers did not know if they could reliably trigger tingles inside noisy fMRI machines—they tried this approach, and subjects seemed to have trouble relaxing—they scanned the resting states of 22 brains as the subjects simply lay there, to see if there were any differences between the two.
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]
