项目摘要
Animals have a keen ability to find odor sources such as food, partners, pups and predators through the sense of smell in a manner that cannot be replicated by machines. How brains mediate navigation of the environment (the odor plume) through smell is an important unsolved problem. Indeed there are many instances where using machines to navigate an odor landscape is an unmet need to society. For example, even though their training requires lengthy one on one interaction with a trainer, dogs are still used to find explosives in airports and in the battlefield. Our multidisciplinary Odor Plume Neurophotonics (OPeN) team will tackle understanding the brain circuits mediating odor plume navigation. This is a daunting task because it involves characterizing how odors diffuse in the air (environmental engineering), developing advanced miniature microscopes to record from the brain of freely moving animals (electrical and mechanical engineering), recording from brain regions processing odor plume information in real time (systems neuroscience and integrative neurophotonics), and developing mathematical procedures to quantify how the information necessary for successful odor plume navigation is represented in the brain (applied mathematics). Our team will engineer a novel miniature microscope to record activity as mice navigate the odor plume and will assess how the activity of these neurons result in successful odor plume navigation. Furthermore, the team members of OPeN are thoroughly committed to foster advancement of women, underrepresented minorities, veterans and disabled individuals in science and participate in various programs to promote science diversity. Additionally, the team members have a track record of disseminating their work and have an established partnership with a local small business, Intelligent Imaging Innovation, Inc. with world headquarters located in Denver. We will continue our commercial dissemination efforts of the technology developed in this project. Finally, we will endeavor to communicate science to the broader audience through venues such as Scientific American, Public Broadcasting Service and outreach through the Denver Museum of Nature and Science.Members of our OPeN interdisciplinary team developed a novel two photon fiber-coupled microscope for 3D imaging of brain activity in the freely moving mouse and generated and quantified realistic odor environments in the laboratory to explore algorithms used for odor-guided navigation. In this project we leverage the extensive expertise and achievements of the team to crack the circuit basis for odor plume navigation. We will develop a low-weight, miniature 3-photon fiber coupled microscope (3P-FCM) to record neuronal activity simultaneously in one brain area in two planes of view. In addition, OPeN will develop a portable photoionization (PID) sensor to detect the odorant concentration at the nostril as the animal navigates the odor plume. Members of the OPeN team will record neural activity in the hippocampus and cerebellum of animals navigating the odor plume and will develop a Bayesian analysis method to decode odor plume navigation from neural activity. This multidisciplinary approach will result in understanding of the brain mechanisms of odor plume navigation.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
动物有一种敏锐的能力,能够通过嗅觉找到食物、伴侣、幼崽和捕食者等气味来源,这种方式是机器无法复制的。大脑如何通过气味来调节环境(气味羽流)的导航是一个重要的悬而未决的问题。事实上,在许多情况下,使用机器来导航气味景观是社会尚未满足的需求。例如,尽管他们的训练需要与训练员进行长时间的一对一互动,但在机场和战场上,狗仍然被用来寻找爆炸物。我们的多学科气味羽流神经光子学(OPEN)团队将致力于了解调节气味羽流导航的大脑电路。这是一项艰巨的任务,因为它涉及确定气味如何在空气中扩散的特征(环境工程),开发先进的微型显微镜来记录自由活动的动物的大脑(电气和机械工程),从大脑区域记录实时处理气味羽状物信息的区域(系统神经科学和综合神经光子学),以及开发数学程序来量化成功气味羽状物导航所需的信息在大脑中的表示方式(应用数学)。我们的团队将设计一种新型的微型显微镜来记录小鼠在气味羽流中导航时的活动,并将评估这些神经元的活动如何导致成功的气味羽流导航。此外,OPEN的团队成员完全致力于促进女性、代表性不足的少数民族、退伍军人和残疾人在科学领域的进步,并参与各种促进科学多样性的计划。此外,团队成员在传播他们的工作方面有良好的记录,并与位于丹佛的世界总部位于丹佛的当地小型企业智能成像创新公司建立了合作伙伴关系。我们将继续对该项目开发的技术进行商业传播。最后,我们将努力通过诸如科学美国人、公共广播服务和丹佛自然与科学博物馆的外联等场所向更广泛的受众传播科学。我们开放的跨学科团队的成员开发了一种新型的双光子光纤耦合显微镜,用于对自由移动的老鼠的大脑活动进行3D成像,并在实验室中生成并量化真实的气味环境,以探索用于气味引导导航的算法。在这个项目中,我们利用团队的广泛专业知识和成就来破解气味羽流导航的电路基础。我们将开发一种低重量、微型三光子光纤耦合显微镜(3P-FCM),以在两个平面上同时记录一个脑区的神经元活动。此外,OPEN将开发一种便携式光电离(PID)传感器,当动物在气味羽流中导航时,该传感器可以检测鼻孔中的气味浓度。开放团队的成员将记录导航气味羽流的动物的海马体和小脑中的神经活动,并将开发一种贝叶斯分析方法,从神经活动中解码气味羽流导航。这种多学科的方法将导致对气味羽流导航的大脑机制的理解。这一奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
