علماء الأعصاب يقتربون من كشف الطبيعة الفطرية لإحساسنا بالوقت

ما يعرفه ريفو عن الخبر

يقترب علماء الأعصاب من كشف ما إذا كان إحساسنا بالوقت سمة فطرية في الدماغ أم نتيجة للتعلم.
استخدم الباحثون نماذج رياضية لمحاكاة نشاط الخلايا العصبية وتبيّن أن الشبكات ذات الإعدادات الصحيحة أنتجت تسلسلات زمنية دون تدريب.
أظهرت التجارب على العضيات الدماغية وجود تسلسلات نبضية منتظمة دون تجربة حسية مما يدعم فرضية الإشارات الزمنية الفطرية.
يساعد فهم هذه الآلية في الربط بين وظائف الخلايا العصبية الفردية والقدرات الأساسية كالذاكرة والتخطيط والحساب.

أظهرت تجارب أجراها سين لو وزملاؤه من جامعة ميشيغان الأمريكية، أن الخلايا العصبية التي تؤرخ مرور الزمن (خلايا الزمن)، قد تكون بنية فطرية في الدماغ.
