An approach for assessing arousal characteristics of ASMR using electroencephalographic power

Autonomous sensory meridian response (ASMR) is a theory that the brain feels a sense of psychological stability by stimulating the five senses. Existing ASMR studies mainly use subjective evaluation such as questionnaires having potential biases. Therefore, objective evaluation needs to be made. To increase objectivity, we determined a biomarker based on electroencephalography. This study found that the characteristics of ASMR depend on arousal. We detected differences in delta waves in the frontal and central areas and gamma waves in the occipital region. This result means that arousal characteristics can be applied to the ASMR biomarker. We anticipate that our study will improve our understanding of objective ASMR characteristics.
