These specific sound - chewing the gum, slurping or sipping noodles could make anger condition called Misophonia (sound sensitivity disease). You are not alone.
For example, many people dislike the sound of scratching a blackboard with a key or nail, it is unbearable for everyone. But on the other hand, there are sounds that are separated by people, whether or not you dislike them. What are the differences between the people with Misophonia and those who are not? New neurological approach, research by Researchers at the University of Newcastle in UK.
There were 42 people including 20 Misophonia and 22 others who participated in the experiment. It studied how the brain responds by listening to various sounds by MRI. First of all, people who were not Misophonia did not show any discomfort to any sound, except a reaction to a specific sound such as baby's cry.
Meanwhile, people with Misophonia who had shown increase level of stress shown every time they listened to every sound in their experiments. The deep emotional reactions (irritability/anxiety) were shown against sounds like slurping food and human breathing. In particular, Fronto Insular Cortex that is hyperactive, responsible for feelings (AIC)
Research results published in Cell Biology show that in the anterior cerebral cortex (AIC) of the cerebrum of Misophonians, the prefrontal cortex (vmPFC), the posterior medullary cortex (PMC), the hippocampus and the posterior medullary cortex An abnormal functional connection with the brain area such as Amygdala. Also, when exposed to chewing sounds or people breathing sounds, It found that amplified galvanic skin response and heart rate
Well, the area of the brain responsible for emotion, manners differ depending on the culture, so it may be necessary to give more attention to the sound, as it is a modern age where research on Mithofonia has progressed.
