brain imaging investigation of the memory-enhancing effect of emotion

أحداث عاطفية تميل الى ان تكون افضل من 1،2 تذكرت أحداث غير عاطفية. هدف واحد من علماء الأعصاب الإدراكي والعاطفي هو فهم الآليات العصبية الكامنة وراء هذا التأثير تعزيز العاطفة على الذاكرة. وهو أسلوب ثبت تأثير كبير في التحقيق في تأثير الذاكرة تعزيز العاطفة هو ما يسمى نموذج الذاكرة اللاحقة (SMP). كانت في الأصل تستخدم هذا الأسلوب للتحقق من يرتبط العصبية غير عاطفية ذكريات 3 ، ومؤخرا نحن وغيرنا أيضا تطبيقها بنجاح لدراسات الذاكرة العاطفية (التي استعرضت في 4 ، 5-7). هنا ، نحن تصف البروتوكول الذي يسمح بالتحقيق في يرتبط العصبية لتأثير الذاكرة تعزيز العاطفة باستخدام SMP بالتزامن مع الحدث المرتبطة التصوير بالرنين المغناطيسي الوظيفي (fMRI). ميزة هامة للSMP هو أنه يتيح الفصل بين نشاط الدماغ المرتبطة تحديدا مع الذاكرة أكثر من نشاط العامة المرتبطة الادراك. وعلاوة على ذلك ، في إطار التحقيق في تأثير المحفزات العاطفية ، SMP يسمح بتحديد مناطق الدماغ النشاط الذي هو عرضة للتعديل والعاطفية على حد سواء الإدراكية / الذاكرة العامة والخاصة المعالجة. ويمكن استخدام هذا البروتوكول في مواضيع صحية 15/08 ، وكذلك في المرضى السريرية حيث توجد تغييرات في الإدراك العصبي يرتبط العاطفة والتحيز في تذكر الأحداث العاطفية ، مثل أولئك الذين يعانون من الاكتئاب واضطراب ما بعد الصدمة الإجهاد (PTSD ) 16 ، 17.

Brain Imaging Investigation of the Memory-Enhancing Effect of Emotion

نقدم البروتوكول الذي يستخدم التصوير بالرنين المغناطيسي الوظيفي للتحقيق في يرتبط العصبية لتأثير الذاكرة تعزيز العاطفة. هذا البروتوكول يسمح التعرف على نشاط الدماغ مرتبطة على وجه التحديد إلى معالجة الذاكرة ذات الصلة ، على عكس المعالجة الإدراكية أكثر عمومية ، ويمكن استخدامها مع السكان الصحية والسريرية.
