There is a kind of webcast that you must wear headphones. The beautiful women inside use some machine similar to ears to transmit all kinds of crisp and pleasant sounds through their own techniques or musical instruments. Asmr (autonomous sensory meridian response), translated as "spontaneous sensory meridian response" in Chinese, is a new word used to describe perceptual phenomena, which is characterized by unique and pleasant stimulation in the brain, scalp, back or other parts of the body. There is great controversy about the nature and classification of ASMR, because although ASMR has a large number of fanatical followers and strong evidence to prove the existence of this phenomenon, there is little or no scientific explanation or experimental data to prove this phenomenon.

Because of ASMR, the audience will experience the feeling of back tingling, scalp numbness and intracranial numbness. Essentially, this is the result of bioelectricity, which can be classified as a special kind of nerve excitement. This feeling can also be defined as a unique sense of excitement, which is considered comfortable and pleasant by some people. To tell the truth, bioelectrical stimulation is really useful and worthy of the description of "brain massage". But for most of these bioelectric currents, the mechanism is not pleasant at all, because another name of ASMR is "creepy".
