This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The goals of this project are to examine the mechanisms involved in the development of neural circuits and compare these mechanisms of neural development to the mechanisms involved in regeneration in zebrafish. The purpose of this project is to determine whether neural regeneration is similar to the process of neural development or whether the two processes represent different mechanisms. The first specific aim of this work is to determine whether the recovery of the retina and tectum following retinal damage follows the same anatomical and physiological sequence found in normal development. The second specific aim is to examine whether environmental factors can modify the sequence of neural development and regeneration. To determine the importance of environmental signals in the developing and regenerating retina, retinoic acid (RA) levels will be altered; RA is a known morphogen necessary for retinal development. The project's significance is that it will provide a better understanding of the relationship between neural regeneration and visual development and has implications for eye health issues and for any eye disease in which retinal damage occurs.

该子项目是利用 NIH/NCRR 资助的中心拨款提供的资源的众多研究子项目之一。子项目和研究者 (PI) 可能已从另一个 NIH 来源获得主要资金，因此可以在其他 CRISP 条目中得到体现。列出的机构是中心的机构，不一定是研究者的机构。该项目的目标是检查神经回路发育所涉及的机制，并将这些神经发育机制与斑马鱼再生机制进行比较。该项目的目的是确定神经再生是否与神经发育过程相似，或者这两个过程是否代表不同的机制。这项工作的第一个具体目标是确定视网膜损伤后视网膜和顶盖的恢复是否遵循正常发育中相同的解剖和生理顺序。第二个具体目标是检查环境因素是否可以改变神经发育和再生的顺序。为了确定环境信号在视网膜发育和再生中的重要性，将改变视黄酸（RA）水平； RA 是一种已知的视网膜发育必需的形态发生素。该项目的意义在于，它将提供对神经再生和视觉发育之间关系的更好理解，并对眼睛健康问题和发生视网膜损伤的任何眼部疾病产生影响。
