CORTICAL PROCESSING OF VISUAL MOTION

我们研究的长期目标是了解神经元 调节视觉感知和视觉引导行为的过程。 为此，我们正在进行平行的行为和生理 在动物身上进行的实验， 或眼球运动任务。 通过记录大脑皮层神经元的活动 在执行这些任务的过程中，我们初步了解了 神经元活动与动物行为能力的关系。 有关这种关系的假设是通过修改神经网络来测试的。 活动在局部皮层电路，以确定行为是否是 以可预测的方式进行。 计算机建模技术是 用于发展更精确的假设， 大脑到行为的转变既严格又可测试。 这种组合 行为、电生理和计算技术的结合， 认知神经生理学研究的现实基础 例如感知、记忆和运动规划。

The long-term goal of our research is to understand the neuronal processes that mediate visual perception and visually guided behavior. To this end we are conducting parallel behavioral and physiological experiments in animals that are trained to perform selected perceptual or eye movement tasks. By recording the activity of cortical neurons during performance of such tasks, we gain initial insights into the relationship of neuronal activity to the animal's behavioral capacities. Hypotheses concerning this relationship are tested by modifying neural activity within local cortical circuits to determine whether behavior is effected in a predictable manner. Computer modelling techniques are then used to develop more refined hypotheses concerning the relationship of brain to behavior that are both rigorous and testable. This combination of behavioral, electrophysiological and computational techniques provides a realistic basis for neurophysiological investigation of cognitive functions such as perception, memory and motor planning.
