 پژوهشگران انگلیسی مکانیزمی را یافتند که از طریق آن سطح پایین سروتونین منجر به بروز خشم می شود و نشان دادند که با خوردن شکلات و تخم مرغ می توان خشم را کاهش داد
به گزارش خبرگزاری مهر، بارها پیش آمده است که صبحها با بدخلقی از خواب بیدار شده اید. اکنون گروهی از دانشمندان دانشگاه کمبریج نشان دادند که بدخلقی به دلیل سطوح انتقال دهنده عصبی سروتونین است که وقتی فرد غذا نخورده باشد نوسان می کند استرسی که در اثر این نوسان ایجاد می شود منجر به بروز خشم و عصبانیت می شود.

این محققان به منظور دستیابی به این نتایج با استفاده از رزونانس مغناطیسی، تاثیرات سطوح سروتونین مغز 30 داوطلب سالم را در پاسخ به تحریکاتی چون چهره های خشمگین، غمگین و یا بیانات خنثی بررسی کردند.

در طول این تحقیقات، دانشمندان سطوح سروتونین داوطلبان را با دستکاری رژیم غذایی آنها تغییر دادند و به خصوص با استفاده از "تریپوفان"، ماده ای که برای تولید سروتونین مطلوب است و به اندازه کافی در سفیده تخم مرغ، بعضی از ماهیها و شکلات وجود دارد این دستکاری را انجام دادند.

سپس با مشاهده فعالیت نواحی مختلف مغز دریافتند که سطوح پایین سروتونین، کورتکس جلوپیشانی را برای کنترل پاسخ خشمی که در بادامه مغز ساخته شده است به شدت دچار مشکل می کند.

این دانشمندان در این خصوص توضیح دادند: "از دهه های قبل می دانستیم که سروتونین نقش مهمی در خشم و پرخاشگری ایفا می کند اما تنها از مدتی قبل فناوری را به دست آورده ایم که می تواند درون مغز را نگاه کند و روشی را که با آن این انتقال دهنده عصبی پالسهای احساسی ما را تنظیم می کند مورد بررسی قرار دهد."

براساس گزارش تکنوراتی، به گفته این محققان، هرچند این نتایج در مورد داوطلبان سالم به دست آمد باوجود این می توانند در خصوص علل بروز طیف وسعیی از اختلالات روانی که در آنها خشم یک عنصر مشترک است توضیح دهد.

This also helps you goal your clients neatly
and focus more on tailoring their needs.

Cocktail rings, for instance, can be worn with traditional apparel for the entire ethnic look
and may also remodel an evening robe with a contact of bling.

How does Achilles tendonitis occur?

I know this if off topic but I'm looking into starting my own weblog and was curious what
all is required to get setup? I'm assuming having a blog like yours
would cost a pretty penny? I'm not very internet smart so I'm
not 100% positive. Any suggestions or advice
would be greatly appreciated. Thank you

With havin so much written content do you ever run into any issues of plagorism or copyright infringement?
My website has a lot of unique content I've either
authored myself or outsourced but it looks like a lot of it
is popping it up all over the internet without my permission. Do you know any techniques to help reduce content
from being stolen? I'd genuinely appreciate it.

I've been browsing online more than 3 hours today,
yet I never found any interesting article like yours. It is pretty worth enough for me.
In my view, if all website owners and bloggers made good content as
you did, the internet will be much more useful than ever before.
How do you get a growth spurt?
