Portable ultrasonic stimulus and neural recording workstation

这项建议要求的设备将使我能够利用声音合成软件和小型化高采样率采集硬件的最新进展，同时广播声音并从神经学上记录昆虫的听觉反应。我的实验室研究昆虫耳朵的听觉神经生理学和感觉生态，主要是飞蛾和蚱蜢对食虫蝙蝠的回声定位呼叫。蝙蝠发出惊人的多样性的高频声音，并以一种准确的方式重现这些声音，这也允许我使用我正在开发的定制的MATLAB应用程序来操作特定的声学变量。*录音公司Avisoft制造高频麦克风和扬声器，使我能够重现在我以前研究过或计划未来研究的世界热带地区发现的罕见蝙蝠物种的声音。针对这些复杂声音测试飞蛾的耳朵将允许我到发现这些蝙蝠的地区进行实地考察(例如，Avisoft的数字数据采集系统还可以用来记录野生蝙蝠在它们的自然栖息地的回声定位叫声，以及监听它们的昆虫的听觉神经活动。现在，这将使用一个现场兼容的工作站来实现，该工作站通过USB连接进行电池操作，完全便携。

The equipment requested in this proposal will enable me to make use of recent advances in sound synthesis software and miniaturized high sample rate acquisition hardware to simultaneously broadcast sounds and neurologically record the auditory responses of insects.  My laboratory investigates the auditory neurophysiology and sensory ecology of insect ears, primarily moths and grasshoppers to the echolocation calls of insectivorous bats.  Bats emit an astonishing diversity of high frequency sounds and reproducing these sounds in an accurate fashion that also allows me to manipulate particular acoustic variables is now possible using a customized MATLAB application that I am in the process of developing.  The sound recording company Avisoft manufactures high frequency microphones and speakers that will enable me to reproduce the sounds of unusual bat species found in tropical regions of the world where I have either previously studied or am planning to study in the future.  Testing moth ears against these complex sounds will allow field trips to the areas where these bats are found (e.g., South Africa, Australia, South America).  Avisoft's digital data acquisition system can also be used to record the echolocation calls of wild bats in their natural habitats as well as the auditory neural activity of the insects that listen for them.  This will now be possible using a field-compatible workstation that is battery operated via USB connections and fully portable.
