INTERNEURON FUNCTION IN THE ZEBRAFISH SPINAL CORD

这个项目的目标是检查它的结构和功能 控制逃逸的网状脊髓系统中的中间神经元 鱼的行为。触发逃逸行为的神经回路 是简单的，涉及相对较少的细胞类型和细胞数量，使得 这是一个适当的系统，可以作为 网状脊髓运动控制。这个项目的几个主要目标 是为了确定网状脊髓系统的神经成分 在斑马鱼中逃逸，并检查几个 中间神经元、连合中间神经元和下行神经元的分类 中间神经元，在逃逸行为中。细胞消融与体内 将使用共聚焦显微镜进行钙成像以解决 这些目标。幼虫斑马鱼将被用作这方面的模型系统 学习。由于它们的身体几乎是透明的，它们是理想的 以及丰富的关于它们生物学各个方面的知识。 该项目将提供斑马鱼神经生物学的基本信息。 以及中间神经元在网状脊髓系统中的作用。

The objective of this project is to examine the structure and function of interneurons in the reticulospinal system controlling escape behavior in fishes. The neural circuit which triggers escape behavior is simple, involving relatively few cell types and cell numbers, making this an appropriate system to use as a case study in the reticulospinal control of locomotion. Several major goals of this project are to determine the neural components of the reticulospinal system for escape in zebrafish and to examine the functions of several classes of interneuron, commissural interneurons and descending interneurons, during the escape behavior. Cell ablation and in vivo calcium imaging with confocal microscopy will be used to address these goals. Larval zebrafish will be used as a model system for this study. They are ideal due to the near transparency of their bodies and the wealth of knowledge available on all aspects of their biology. This project will provide basic information on zebrafish neurobiology and on the roles of interneurons in reticulospinal systems.
