项目摘要
Project Summary/Abstract
Animals have evolved specialized neural circuitry that links sensory input to neuroendocrine and behavioral
responses. The proper function of these systems is essential for the health and wellbeing of individuals.
Sensory inputs controls some fundamentally important innate behaviors, including mating, aggression and
parental behaviors. Dysfunction in these circuits may lead to depression, mood disorders, sexual dysfunction,
and aberrant parental behaviors. Here we propose to study the neural circuits that detect and process
pheromone information and regulate endocrine and behavioral responses in rodents. In vertebrates,
pheromone cues can directly trigger mating rituals and territorial aggression. Many terrestrial species have
evolved highly sophisticated vomeronasal systems to detect pheromones. The vomeronasal circuit connects
directly to the endocrine systems and influences their output. These circuits are largely genetically determined
and there is an intrinsic link between sensory input and the behavioral responses. The mouse vomeronasal
circuitry, therefore, serves as an ideal model system to elucidate the neural mechanism of sensory information
processing, mechanism of neuroendocrine control and sensory control of innate behaviors. Similar circuits
exist in humans but may have been compacted during primate evolution to consist of mostly the main olfactory
system, and to include other sensory modalities. The study of the vomeronasal system can provide a roadmap
to understand these more complex circuits.
The objective of this application is to delineate the vomeronasal circuitry that detects and processes
information of two classes of female pheromones. The proposal is based on our study identifying two sets of
vomeronasal receptors recognizing pheromones cues that convey the sexual identity and the estrus status of
female mice, respectively. In this study, we will determine the contribution of vomeronasal sensory neurons
(VSNs) expressing these receptors to sexual behaviors. We will investigate and determine the connectivity
diagram between the VSNs and the mitral cells in the accessory olfactory bulb. We will also identify the brain
regions and specific cell populations that process information conveyed by these cues and map their
connections. These studies are expected to reveal highly specific neural circuits that control mating behaviors
项目总结/摘要
动物已经进化出专门的神经回路,将感觉输入与神经内分泌和行为联系起来。
应答这些系统的正常运作对个人的健康和福祉至关重要。
感官输入控制着一些基本上重要的先天行为,包括交配、攻击和
父母的行为这些回路的功能障碍可能导致抑郁症、情绪障碍、性功能障碍,
和异常的父母行为在这里,我们建议研究神经回路,检测和处理
信息素的信息和调节内分泌和行为反应的啮齿动物。在脊椎动物中,
信息素线索可以直接触发交配仪式和领土侵略。许多陆地物种
进化出高度复杂的犁鼻系统来探测信息素。犁鼻回路连接着
直接进入内分泌系统并影响其输出。这些电路在很大程度上是由基因决定的
在感官输入和行为反应之间有一种内在的联系。小鼠犁鼻器
因此,神经回路是阐明感觉信息的神经机制的理想模型系统
加工、神经内分泌控制机制和先天行为的感觉控制。类似的电路
存在于人类中,但可能在灵长类动物进化过程中被压缩,主要由主要的嗅觉器官组成。
系统,并包括其他感官形式。犁鼻系统的研究可以提供路线图
来理解这些更复杂的电路。
本应用的目的是描绘犁鼻电路,检测和处理
两类雌性信息素的信息。这项建议是基于我们的研究,确定了两套
犁鼻受体识别信息素线索,传达性别身份和发情状态的
雌性小鼠,分别。在这项研究中,我们将确定犁鼻感觉神经元的贡献
(VSNs)表达这些受体的性行为。我们会调查并确定
副嗅球中VSN和二尖瓣细胞之间的示意图。我们还将鉴定
区域和特定的细胞群,处理这些线索传达的信息,并映射它们的
连接.这些研究有望揭示控制交配行为的高度特异性神经回路
