(2021·安徽太湖中学质检)Can't you stand the sound of heavy breathing or sipping soup? Does the sound of someone chewing gum next to you make your blood boil? You are not alone, but you are not going crazy—there's a really scientific reason why.
If you shrink back when someone twists their knuckles(指关节), you might want to get checked out for misophonia, a brain abnormality that creates “a hatred of sounds such as eating, chewing, loud breathing, or even penclicking,” TIME reports. Actually, it's just one of the strange habits that prove you're smarter than everyone else. Although researchers first coined the term misophonia in 2001, doubt has been thrown on it by the medical community. But thanks to recent research, it can be safely drawn that everyday noises can ruin people's lives. A team at Newcastle University in the U.K.examined MRI brain scans (核磁共振脑扫描) of those with and without misophonia while playing a range of sounds. The sounds were either neutral (like rain or water boiling), unpleasant (a baby crying or a person screaming), or trigger sounds (the sounds of breathing or eating).
The researchers noted significant changes in misophonia sufferers' brain activity when they heard a “trigger sound.” Turns out, those with misophonia have a developmental difference in their brains frontal lobe(额叶) that causes their brains to react harshly to those triggers. It also causes them to sweat and their heart rates to increase.
“For many people with misophonia, this will come as welcome news as for the first time we have shown a difference in brain structure and function in sufferers.” said Dr Sukhbinder Kumar. “This study shows the critical brain changes as further evidence to convince a skeptical medical community that this is a real disorder.”
