RUI: Evolution of Forebrain Systems

德姆斯基 97-24144 大脑进化的标志是大脑最前端部分端脑的大小和复杂性的增加，以及感觉系统的扩展和整合。这种模式在几种生物中很明显。调查和比较不同的生物体如何实现这一点，可以深入了解人类大脑的进化，以及系统处理大量复杂信息的不同方式。这个项目研究视觉和听觉系统的进化。神经解剖学研究描述了视觉和听觉系统的连接，以及这些系统如何在前脑中融合和整合。生理学研究表明，这种收敛如何导致与正在进行的行为相关的复杂神经活动模式。这项研究的结果增加了对大脑进化的理解，以及对大脑如何比较来自多个来源的信息以获得外部世界的综合表征的理解。

Demski 97-24144 The evolution of the brain is marked by an increase in the size and complexity of the front-most portion of the brain, the telencephalon, as well as the expansion and increased integration of sensory systems. This pattern is apparent in several lines of organisms. Investigating and comparing how different organisms accomplish this provides insight into the evolution of the human brain as well as information about the different ways systems can process high volumes of complex information. This project examines the evolution of visual and auditory systems. Neuroanatomical studies describe the connections of visual and auditory systems and how these systems converge and are integrated in the forebrain. Physiological studies indicate how this convergence results in complex patterns of neural activity related to ongoing behavior. Results of this research add to the understanding of the evolution of the brain and to the understanding of how the brain compares information from multiple sources to arrive at an integrated representation of the external world.
