نوبل الطب 2026… كيف أصبح «علم البصريات الوراثي» مفتاحاً لفك أسرار الدماغ؟

ملخص الخبر

فاز كارل ديسيروث وبيتر هيغيمان وجيورج ناغل بجائزة نوبل لعام 2026 لابتكار تقنية علم البصريات الوراثي.
تسمح هذه التقنية للعلماء باستخدام الضوء لتشغيل أو إيقاف نشاط خلايا عصبية محددة داخل الدماغ الحي.
تساعد التقنية في دراسة علاقات السبب والنتيجة في الذاكرة والمشاعر والسلوكيات وتحديد الدوائر العصبية المسؤولة عنها.
تفتح التقنية آفاقاً علاجية واعدة لاستعادة البصر وعلاج اضطرابات عصبية ونفسية مثل الصرع والباركنسون والاكتئاب.

ملخص كتبه الذكاء الاصطناعي من نص الخبر في مصدره.

لطالما حلم العلماء بفهم الطريقة التي يصنع بها الدماغ الذكريات والمشاعر والسلوكيات، وكيف يمكن لعضو لا يتجاوز وزنه نحو 1.3 كيلوغرام أن يخزن تجارب الطفولة.
