项目摘要

IBN: 9634368 PI: McLaughlin This project will be supported under the NSF program on INTEGRATING ENABLING TECHNOLOGIES INTO NEUROSCIENCE RESEARCH; it is a collaboration of mathematicians and neuroscientists attacking the most important issues in brain research. In our view, the premier problem facing us is how to understand the function of the cerebral cortex of the brain as a functioning neural network. We study the part of the cerebral cortex that handles visual information--called the visual cortex. Cells in the visual cortex are selectively sensitive for the orientations of the visual boundaries of objects. We will develop and test neural network models for this selectivity, to see whether it is a property that emerges from interactions between nerve cells in the cerebral cortex, or whether it is a passive by-product of the connections to cortical cells from lower levels of the visual system of the brain. We believe that understanding the neural basis for orientation tuning in the visual cortex may be crucial for understanding the function of the entire cortex. If we find evidence that interaction between neighboring neurons in the cerebral cortex is essential for orientation tuning to work, then this will be crucial support for the idea that the cerebral cortex is a richly interconnected, interactive neural network that can be studied with available analytical tools.

IBN：9634368 PI：McLaughlin这个项目将在NSF计划下支持将启示技术集成到神经科学研究中；这是数学家和神经科学家的合作，攻击大脑研究中最重要的问题。我们认为，我们面临的主要问题是如何理解大脑的大脑皮层作为功能性神经网络的功能。我们研究处理视觉信息的大脑皮层的一部分，该部分被视觉皮层。视觉皮层中的细胞对物体可视边界的方向有选择性地敏感。我们将开发和测试这种选择性的神经网络模型，以查看它是否是从大脑皮质中神经细胞之间的相互作用中出现的特性，还是它是从大脑视觉系统较低水平的与皮质细胞的连接的被动副产品。我们认为，了解视觉皮层中定向调整的神经基础对于理解整个皮质的功能至关重要。如果我们发现有证据表明，大脑皮层中相邻神经元之间的相互作用对于定向调整至关重要，那么这将是至关重要的支持，即大脑皮层是一种可以使用可用的分析工具研究的富有互连的交互式神经网络的观念。
