ما الذي يجري في الدماغ خلال الضحك؟

ملخص الخبر

كشفت دراسة حديثة عن وجود شبكتين دماغيتين متمايزتين تماما للضحك الإرادي والضحك اللاإرادي.
الضحك اللاإرادي يرتبط بشبكة عصبية قديمة توفر شعورا بالمتعة وتخفيف الألم وتعد من الأصوات العاطفية التلقائية.
الضحك الإرادي يرتبط بشبكة حركية بشرية معقدة تستخدم للتواصل الاجتماعي وتعمل كعلامة ترقيم منطوقة في المحادثات.
يختلف الضحك الإرادي عن اللاإرادي في النبرة والمدة والتحكم الحركي والارتباط بالأنظمة العصبية الكيميائية.

ملخص كتبه الذكاء الاصطناعي من نص الخبر في مصدره.

يُعدّ الضحك وإن ارتبط غالبا بالمرح ظاهرة معقدة، فكثيرا ما يتملكنا بشكل لا إرادي حتى في مواقف غير متوقعة.
