| ASMR doesn’t seem to work for everyone in the population. It can be tough to imagine the sensation if you don’t experience it first-hand (The ASMR, n.d). For the population that does experience ASMR, they get a blissful tingling starting up in the scalp and the making its way through the body (The ASMR, n.d). The public interest in ASMR has risen dramatically over the past couple of years. This also resulted in what they called themselves practicing “ASMRtists” to promote relaxation and sleep (Poerio et al.,2018). | ASMR doesn’t seem to work for everyone in the population.

| Evidence shows that Autonomous Sensory Meridian Response is a very complex phenomenon that consists of various physiological parameters (Poerio et al.,2018). Neuroimaging research has revealed trait-level differences in resting-state brain activity between people who experience ASMR (Poerio et al.,2018). For the population that experiences ASMR, it has been shown that there is reduced and increased connectivity in a number of areas called Default Mode Network (DMN) (Poerio et al.,2018). Default Mode Network consists of angular gyri, posterior cingulate, medial temporal gyri, bilateral inferior/ parietal cortices and medial prefrontal cortices (Smith et al.,2017). This network around the brain is linked with internal mental activity and self- referential processing (Poerio et al.,2018). | Evidence shows that Autonomous Sensory Meridian Response is a very complex phenomenon that consists of various physiological parameters (Poerio et al.,2018).

| Even in FMRI, study results coincide with the above results. DMN of individuals with ASMR showed significantly less connectivity and increased connectivity around specific regions of the DMN (Smith et al., 2017). | Even in FMRI, study results coincide with the above results.

Panels A and B represent synesthetes and control subjects respectively. The circled areas refer to brain regions functionally connected to V4 in synesthetes, but not in controls. Overall the functional connectivity of V4 with other brain regions, particularly those associated with visual color sensation, is more pronounced in synesthetes (Dovern et al., 2012).> | + | </box| Figure 4: 3-D surface rendering of brain regions functionally connected with bilateral visual area V4 in grapheme-color synesthetes.

| Autonomous sensory meridian response has recently become well-known. The science of ASMR is complex as it relates to physiological parameters. ASMR for babies is commonly used with over 10 million ASMR videos available online. Not everyone responds to ASMR, some people have reported a disgusting feeling in association with it. Sometimes ASMR can be mentally debilitating, which is why precautions must be taken when seeking ASMR as a therapeutic intervention. It is also used to help cope with anxiety and stress. Overall, ASMR is perfectly safe and can be potentially effective. | Autonomous sensory meridian response has recently become well-known.
