9981709WilkensThis award supports Lon Wilkens and a graduate student from the University of Missouri-St. Louis in a collaboration with Leo van Hemmem of the Department of Physics at the Technical University of Munich, Germany. The collaboration seeks to understand the neural mechanisms which underlie passive electrosensory detection and capture of planktonic prey by paddlefish. That fish has a unique, elongated rostrum which has recently been shown to act as an antenna in plankton feeding. The paddlefish is an ideal subject for studying the neural mechanisms which map the sensory environment since the paddlefish sensitivity to electric fields is acute and provides sensory information necessary for accurate feeding strikes by juvenile fish in the absence of other sensory inputs. Neuroanatomical and electophysiological experiments will provide parameters for modeling the peripheral electroreceptive system and for characterizing peripheral sensitivity to natural planktonic prey. The collaboration will combine the theoretical modeling expertise of the German group with the experimental capabilities of the U.S. side.

9981709 Wilkens该奖项支持Lon Wilkens和密苏里大学圣路易斯分校的一名研究生与德国慕尼黑工业大学物理系的Leo货车Hemmem合作。 该合作旨在了解白鲟被动电感觉检测和捕获无张力猎物的神经机制。 这种鱼有一个独特的，细长的喙，最近被证明是浮游生物进食的天线。 白鲟是一个理想的主题，用于研究神经机制，映射的感觉环境，因为白鲟的敏感性电场是急性的，并提供必要的感官信息，准确的饲料罢工的幼鱼在没有其他感官输入。 神经解剖学和电生理学的实验将提供参数的外周电感受系统的建模和表征外周的敏感性，以自然的电刺激猎物。 该合作将联合收割机德国集团的理论建模专业知识和美国方面的实验能力。
