Functional Anatomy of Frog Tecto-motor Systems

如何将（大脑中的）空间映射信息转化为时间有序的运动模式，是大卫·英格尔博士领导的研究项目的长期目标。为了实现这一目标，他目前正在使用两栖动物，并对进食和回避行为的组成部分进行详细的运动学分析。他将对这些行为的假定神经基础进行新的解剖学研究。通过对某些大脑结构损伤产生的行为缺陷的分析，他可以检验目前的假设，即捕捉猎物和躲避行为的特定组成部分是如何与特定脑神经投射的组成部分相关的。这项工作很重要，因为英格尔博士正在研究脊椎动物的下脑干，关于这些神经回路及其与定向运动的关系的分析很少。对脊椎动物定向行为的感觉控制的分析是英格尔博士的专长，他所做的工作将大大增加我们在这一领域的知识。

How spatially-mapped information (in the brain) can be transformed into temporally ordered patterns of movement is the long term objective of the research program headed up by Dr. David Ingle. To achieve this end he is currently using amphibians and doing detailed kinematic analysis of components of feeding and avoidance behaviors. He will undertake new anatomical studies of the presumed neural substrate of these behaviors. Through an analysis of behavioral deficits produced by lesions of certain brain structures he can test current hypotheses as to how particular components of prey-catching and avoidance behaviors are related to components of specific brain neural projections. This work is important because Dr. Ingle is working on the lower brainstem of vertebrates and little analysis is available regarding these neural circuits and their relationship to directed movements. The analysis of sensory control of orienting behaviors in vertebrates is the expertise of Dr. Ingle and the work to be performed should greatly increase our knowledge in this field.
