从体全息存储原理出发,列举了体全息存储的技术和主要的几种系统结构,并就同轴式全息存储系统原理、系统结构、编码方式进行了详细的介绍分析。在未有成熟的相位编码方式的情况下,对基于相位调制的同轴全息存储系统的两种相位编码方式进行了分析评价,这两种相位编码方式对全息存储中相位编码的可能实现方式进行了有效补充,其组合式相位编码方式与传统振幅编码相比提高了编码率且降低了误码率。另外,介绍和分析了一种可以有效减少材料消耗并提高存储密度的多阶复振幅调制的同轴全息存储系统,并对其系统表现性能进行评价。综合评价得出,更合理的编码方式、适当的调制手段和抑制噪声仍是现在全息存储研究中亟待解决的问题。

记忆巩固通常在记忆编码后的休息或睡眠期间缓慢发生。然而,在应激状态下,记忆有可能被快速巩固。鉴于长期以来缺乏对人类记忆巩固期神经活动的量化方法,应激状态下记忆快速巩固的机制尚未明确。本研究拟采用计算神经科学手段,详细刻画应激状态下人类情景记忆巩固期的神经重放过程。此外,我们还将整合认知心理学、脑成像技术、机器学习、神经内分泌调控、应激诱发及生理生化检测等跨学科方法,来验证应激对神经重放的“双刃剑”效应假说:尽管应激可能会加快神经重放的速度,促进记忆巩固,但它同时也可能会降低神经重放的准确性并干扰其顺序。本研究将:(1)比较应激和非应激状态下神经重放的多维特征差异;(2)探寻应激状态下神经重放与记忆提取和编码的交互作用;(3)尝试利用神经内分泌和环境策略来调控人类的应激反应,进而影响神经重放。本研究能够有助于确定促进记忆巩固的理想大脑状态,并整合人类和动物的神经重放研究。同时,本研究还可能为保护应激状态下的情景记忆功能,以及干预应激类精神疾病中的记忆障碍提供全新策略。
