结构决定功能是生物学的基本原理之一。体现在神经系统中,大量神经元彼此连接所形成的精细复杂的神经网络是实现神经计算,涌现出感知、情感、记忆、决策等复杂行为现象的物质基础。因此,解析连接与计算的关系,是深入理解生物智能的关键钥匙。围绕这一问题,本课题组从以下几个方面展开研究:
1. 新型脑连接组绘制技术的开发
以单细胞精度高通量解析神经元的连接模式,并实现连接信息与神经活动、基因表达等信息的整合,是系统神经科学面临的重大技术挑战。我们将基于前期工作基础,推进基于DNA条形码的高通量、跨模态脑连接组学技术。我们期待这些技术为系统神经科学研究带来新的实验范式。
2. 自然行为调控的神经机制
自然行为,如防御行为、社会行为等,对于动物的生存繁衍有着至关重要的意义,而自然行为的失调也与焦虑症、抑郁症等精神障碍密切相关。我们关注小鼠在复杂情境中自然行为的调控与表达,结合定量行为学、系统神经科学、连接组学和计算神经科学,解析自然行为调控的行为学逻辑,阐明自然行为及相关精神疾病中的神经环路的编码与动力学特征。
3. 发育连接组学
相比于需要大量数据、耗费大量能量才能具有较好泛化性的人工神经网络,神经系统从组装到具备生物智能的发育过程惊人的高效。而在进化过程中得到高度优化的发育程序,很可能是大脑能够形成精密且高效的连接网络的关键。本课题组关注连接组的发育过程与组装机制,期待从发育连接组学的视角揭示背后的奥秘。
