DESCRIPTION: The goal of this study is to study directional hearing in fish, using the sleeper goby as the model. It has five aims: 1. Determine the structural polarity of sensory hair cells in each otolithic organ in 3D space using LEM and SEM. 2. Determine if individual end organs play differential roles in encoding sound direction along different planes. 3. Make structure-function relationships by dye-filling ganglion cells from which directional sensitivity had been assessed by intracellular recordings. 4. Identify any particular direction in which the fish is particularly sensitive and measure MAAs. 5. Determine the contribution of each end organ to the pattern of directional hearing.

描述：这项研究的目的是研究方向听力 鱼，使用卧铺戈比作为模型。 它有五个目标：1。确定 3D中每个耳石器官中的感觉毛细胞的结构极性 使用LEM和SEM的空间。 2。确定单个器官是否在玩 沿不同平面编码声音方向的差异作用。 3。 通过染料填充神经节细胞从 通过细胞内记录评估了哪些方向灵敏度。 4.确定尤其是鱼的任何特定方向 敏感和测量MAA。 5。确定两端的贡献 器官到定向听力的模式。
