The areas that typically work together weren’t firing together as much. Instead, other areas of the brain were getting more involved than usual—areas related to a visual network, for instance. These differences suggest “that instead of having distinct brain networks the way you or I would, there was more of a blending of these networks,” says Smith, who studies the neuroscience of emotion. “It does make intuitive sense that a condition associated with atypical sensory association and atypical emotional association would have different wiring in the brain.”
Over at Shenandoah University in Winchester, Va., Craig Richard, a professor of biopharmaceutical sciences, runs the clearinghouse website ASMR University, where he interviews people who’ve studied the phenomenon and blogs about ASMR in the news. Richard himself reports experiencing ASMR; nevertheless, he says scientific skepticism is warranted until more studies are published. To that end, Richard and two other researchers, Allen and a graduate student, have been conducting an online survey that he says so far includes 20,000 people across over 100 countries, almost all of them “tingleheads.”
Barratt and Davis don’t see their study as a complete story; rather, it’s a foot in the door for researchers interested in studying the phenomenon. “We hope our work will provide a platform for more sophisticated work in the future, but we saw it as a starting point,” explains Davis. The next step, ideally, is to start trying to pin down the physiological basis of the sensation.
What is ASMR? For a trend so wildly popular, you probably haven’t heard of it. ASMR stands for Autonomous Sensory Meridian Response, and it’s a strange recent phenomenon. We all find certain sounds mentally and physically stimulating—some things send a shiver down our spines, create a sensation in the back of our heads. ASMR is a type of sensory stimulus that helps you to relax! In fact, there’s an entire section of Youtube videos and sound creation that is meant to help people feel good. 
When your hungry or when your thristy, upon drinking or eating your brain feels allot better. When consuming it your brain triggers natural dopamine activations in the brain signaling a rewarding behavior. (note that this is done on a regular basis when using alcohol or drugs, where the drug invades the brain dopamine receptors thus requiring a higher dose of whatever the person took, to get the same experience.

Many of those who experience ASMR report that some specific non-vocal ambient noises are also effective triggers of ASMR, including those like the sound of rain, fingers scratching or tapping a surface, the crushing of eggshells, the crinkling and crumpling of a flexible material such as paper, or writing. Many YouTube videos that are intended to trigger ASMR responses capture a single person performing these actions and the sounds that result.[15]
