The Vestibulo-Ocular System in Cartilaginous Fishes

所有脊椎动物都有一个反射反应系统，使它们在头部移动时稳定眼睛，这被称为前庭-眼反射（VOR）。控制反射的大脑回路在所有脊椎动物中都是相似的，除了在某些鱼类（“板鳃目”）中有所不同。有了这个奖项，Rick Puzdrowski博士将进行实验，以确定elasmobranch的VOR电路的形式是该群体的独特专门化，还是所有其他脊椎动物的电路都可能从一个基本的电路计划进化而来。这将通过检查与elsamobranch相关的鱼类VOR回路的解剖学和生理学细节来完成。这项研究提供的信息将为我们提供重要的见解，了解我们大脑的基本运作是如何在进化过程中形成的。＊＊＊

9421393 Puzdrowski All vertebrate animals possess a reflex response system that allows them to stabilize the eyes as the head is moved -- referred to as the vestibulo-ocular reflex (VOR). The brain circuits which control the reflex are similar throughout vertebrates with the exception that they are somewhat different in certain fishes (the "elasmobranchs"). With this award Dr. Rick Puzdrowski will conduct experiments to determine if the form of the elasmobranch VOR circuit is a unique specialization of that group, or instead is a fundamental circuit plan from which the circuits of all other vertebrates may have evolved. This will be accomplished by examining details of the anatomy and physiology of the VOR circuits in fish related to the elsamobranchs. The information provided by this research will give us important insights into how the fundamental operations of our brains were built-up during the course of evolution. ***
