中文摘要
摘要:
社交互动对于人类健康和整个社会来说都是至关重要的。然而,对于许多人来说,这是神经和电路的基础。
社交行为仍然是不确定的。除了经典的社交行为,如攻击性、夫妻关系、亲子关系和父母教养方式,还有。
最近的一项研究也表明,啮齿类动物也有能力改变行为,以帮助安慰陷入困境的个人。
为了更好地研究这些亲社会行为的神经基础,我们最近修改了一项新的协议,该协议可以产生更多的安慰--
就像这种行为在社会上和一夫一妻制的草原田鼠中一样,草原田鼠也被广泛使用在C57BL/6J小鼠身上。这是我们的初步研究。
实验表明,下丘脑(PVT)的下丘脑室旁核(PVT)在神经控制中起着重要作用。
在小鼠身上也出现了类似安慰的行为。在新的PVT中,令人安慰的是一个痛苦的笼子引发了强有力的c-Fos表达。
而对PVT患者的药物遗传抑制作用显著减少了安慰类行为。这是基于这些因素。
耐人寻味的结果是,我们可以提出在活体(Aim1)中执行记录功能的电生理学和光遗传学操作。
在安慰类动物行为中,PVT的作用也很大。在安慰小鼠的过程中,也有很强的作用。
前额叶皮质和腹侧下丘脑的激活是控制PVT的主要输入。因此,我们建议。
为了(AIM2)在亲社会的行为过程中识别PVT活动的主要投入和责任人,并扩大我们的理解。
大多数电子线路正在使用病毒追踪。但是,拟议中的研究将定义更多亲社会的神经电子线路,这将进一步增加信息。
知识库是治疗有社会经济缺陷的疾病的必要基础。
英文摘要
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.
