项目摘要
Abstract
Social interactions are essential for human health and society. However, the neural circuitry basis for many
social behaviors remains uncertain. Beside classical behaviors such as aggression, pair bonding and parenting,
recent research has demonstrated that rodents are also capable of behaviors to comfort distressed individuals.
To study the neural basis of these prosocial behaviors, we recently adapted a protocol that produces consolation-
like behavior in socially monogamous prairie voles to the widely used C57BL/6J mice. Our preliminary
experiments indicate an important role for the paraventricular nucleus of the thalamus (PVT) in controlling
consolation-like behavior in mice. Comforting a distressed cagemate elicited robust c-Fos expression in the PVT
and pharmacogenetic silencing of the PVT dramatically reduced consolation-like behavior. Based on these
intriguing results, we propose to (Aim1) perform in vivo electrophysiology recording and optogenetic manipulation
of PVT to determine the role of PVT during consolation-like behavior. In comforting mice, there was also strong
activation of the prefrontal cortex and ventral subiculum which are major inputs to the PVT. We therefore propose
to (Aim2) identify the inputs responsible for PVT activity during prosocial behavior and expand our understanding
of the circuitry using viral tracing. The proposed studies defining the prosocial neural circuitry will add to the
knowledge base necessary for treating conditions with social deficits.
摘要
社会互动对人类健康和社会至关重要。 然而,许多人的神经回路基础
社会行为仍然不确定。除了经典的行为,如攻击,配对和养育,
最近的研究表明,啮齿类动物也能够做出安慰痛苦个体的行为。
为了研究这些亲社会行为的神经基础,我们最近采用了一种产生安慰性行为的方法。
我们的初步研究表明,在社会性一夫一妻制的草原田鼠中,
实验表明丘脑室旁核(PVT)在控制
小鼠的安慰行为。安慰一个痛苦的cagglutinin引起了PVT中c-Fos的强烈表达。
药物遗传学沉默的PVT显着减少安慰剂样行为。 基于这些
有趣的结果,我们建议(Aim 1)进行在体电生理记录和光遗传操纵
的PVT,以确定在安慰行为的PVT的作用。在安慰小鼠,也有很强的
前额叶皮层和腹侧下托的激活是PVT的主要输入。因此,我们建议
(目标2)确定在亲社会行为期间负责PVT活动的输入,并扩展我们的理解
使用病毒追踪的电路。 拟议中的定义亲社会神经回路的研究将增加
治疗社会缺陷所需的知识基础。
