In animals, normal limb movements such as walking or reaching require sensory information from the limb regarding their movements and mechanics. While fishes use their limbs (or paired fins) for a diverse array of behaviors, little is known about the role sensory abilities plays in those functions. This project examines the fundamental question of how the sensory and motor elements of the fin propulsive system co-adapt to generate a functional neuromechanical system. In particular, it will determine how physical properties of the fins such as stiffness, size and shape, are reflected in the biological instrumentation of the fins for sensation. In addition to providing a new tractable model for studying integration of sensation and movement, data from this project will inform the design of fin-inspired propulsive devices for underwater vehicles. The broader impacts of this project will provide outreach experiences for children on the South Side of Chicago as well as opportunities for undergraduate and graduate training in the laboratory and builds educational activities at the Field Museum of Natural History.

在动物中，正常的肢体运动（例如步行或到达）需要肢体的感官信息，以了解其运动和力学。 尽管鱼类将四肢（或配对的鳍）用于各种各样的行为，但对这些功能的角色感官能力却鲜为人知。 该项目研究了FIN推进系统的感觉和运动元件如何共同适应以生成功能性神经力学系统的基本问题。 特别是，它将决定鳍片，大小和形状等鳍片的物理特性如何反映在鳍片的生物学仪器中进行感觉。 除了提供一个可用于研究感觉和运动整合的新型模型外，该项目的数据还将为水下车辆的鳍启发性推进设备设计。该项目的更广泛的影响将为芝加哥南侧的儿童提供外展经验，以及在实验室的本科和研究生培训的机会，并在自然历史博物馆建立教育活动。
