The Vestibulo-Ocular System in Cartilaginous Fishes

9421393普兹德罗斯基所有脊椎动物都有一种反射反应系统，可以在头部移动时稳定眼睛--称为前庭-眼睛反射(VOR)。控制反射的大脑回路在所有脊椎动物中都是相似的，不同之处在于它们在某些鱼类(“鳍鳍”)中略有不同。获得这一奖项后，里克·普兹德罗斯基博士将进行实验，以确定弹性脊椎动物VOR回路的形式是该群体的独特专长，还是所有其他脊椎动物的回路可能是从其进化而来的基本回路计划。这将通过研究鱼类中与Elsamobranch相关的VOR回路的详细解剖和生理学来实现。这项研究提供的信息将给我们提供重要的见解，让我们了解我们大脑的基本操作是如何在进化过程中建立起来的。***

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. ***
