Portable ultrasonic stimulus and neural recording workstation

本提案中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，同时广播声音和神经学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学，主要是飞蛾和蚱蜢对食虫蝙蝠回声定位的叫声。 蝙蝠发出的高频声音的惊人的多样性和再现这些声音在一个准确的方式，也允许我操纵特定的声学变量，现在可以使用一个定制的MATLAB应用程序，我在开发的过程中。 录音公司Avisoft生产高频麦克风和扬声器，使我能够重现在世界热带地区发现的不寻常蝙蝠物种的声音，我以前研究过或计划在未来研究。 测试飞蛾的耳朵对这些复杂的声音将允许实地考察这些蝙蝠被发现的地区（例如，南非、澳大利亚、南美洲）。 Avisoft的数字数据采集系统还可用于记录野生蝙蝠在其自然栖息地的回声定位呼叫以及倾听它们的昆虫的听觉神经活动。 现在，这将有可能使用一个现场兼容的工作站，是通过USB连接电池供电和完全便携式。

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.
