记忆是人类认识世界、获取知识、掌握技能的基础。记忆原理解析是实现脑科学从基础研究到转化应用的关键,相关研究连续入选Science公布的125个最具挑战性的科学问题。科学家们前赴后继,不断追寻“记忆如何存储和提取”、“能否数字化存储、操控和移植人类记忆”这些基础和应用问题的答案。从医学上讲,记忆的动态调控是理解慢性疾病症状演变和机能复健的重要突破口。课题组围绕“记忆原理及应用研究”总方向,依托研究院在脑科学交叉、融合和转化方面的优势,推进现代分子生物学、先进显微镜光学、细胞生物学等相关技术在记忆原理解析中的创新应用,选取情绪记忆、摄食记忆、运动记忆等包含不同内容的记忆模型作为攻关对象,从多维度解析记忆痕迹的基本特征及其神经生物学基础,以重构与合成为目标刻画情绪情感、营养代谢、运动行为等正常生命活动及其障碍发展的生理本质;同时,开拓记忆原理在脑-体交互调节中的应用,以记忆的视角审视慢性神经精神疾病的症状演变和康复;探索外周或中枢规律性刺激使大脑活性发生“记忆”样长程改变的新模式及其可塑性机理,解析脑内具有明确促康复作用的特征性细胞集群的活性演化过程及其分子驱动力,发展基于记忆原理的疾病干预新策略,推进临床转化应用;打造以记忆研究为特色,引领国际脑科学和生物医药领域发展的研究队伍。具体包括:
1、解析记忆在分子、神经环路和网络等不同尺度的痕迹基础;
2、以记忆的视角研究慢性神经精神疾病的症状演变及其康复;
3、发展记忆研究的新方法和基于记忆原理的疾病干预新策略。
