IBN: 9723542 PI: ATEMA Smell and taste are senses that detect chemicals in the environment, but they do not work in isolation. In the aquatic environment with high viscosity compared to air, chemical "plumes" are carried in currents and can have complex spatial and temporal structure over long distances. Animals in the water are subject to hydrodynamic stimulation by water currents as well, and it is largely unknown how the tactile stimulation from a swift current may affect the chemosensory input, compared to the same chemosensory signal in gently drifting water. This project uses a multidisciplinary approach incorporating hydrodynamics, ultrastructural anatomy and electrophysiology on a crustacean as a model invertebrate chemosensory system. Morphological types of sensory cells in the appendages such as the antenna will be identified, and tested for physiological sensitivity to combinations of chemosensory signals and mechanosensory stimuli. Results will help determine how peripheral integration of multimodal signals might occur, will be important beyond chemosensory science to sensory neuroscience in general, and will have potential applications for technological development of robotic sensory devices.

IBN：9723542 PI：Atema的气味和味道是检测到环境中化学物质的感觉，但它们不隔离起来。 与空气相比，在粘度高的水生环境中，化学“羽”是在水流中携带的，可以在长距离内具有复杂的空间和时间结构。 水中的动物也受到水流的流体动力刺激，与在轻轻漂流水中的相同化学体积信号相比，迅速电流的触觉刺激如何影响化学体积输入。 该项目采用多学科方法，该方法融合了甲壳类动物的流体动力学，超微结构解剖学和电生理学，作为模型无脊椎动物化学感应系统。 将鉴定出附属物（例如天线）中的感觉细胞的形态类型，并测试生理对化学感觉信号和机械感觉刺激组合的敏感性。 结果将有助于确定多模式信号的外围整合是如何发生的，从化学感应科学到一般的感觉神经科学将是重要的，并且将在机器人感觉设备的技术开发中具有潜在的应用。
