Neural mechanisms for visual perception of speed during selfmotion

了解大脑如何处理视觉图像是神经科学的一个基本问题。当我们在世界上不断地移动时，视觉场景的变化主要是由我们自己的运动产生的。这对于与运动和流动相关的视觉特征来说尤其如此，我们对速度的感知也会因运动而改变。然而，视觉感知传统上是在静止的被试中研究的，在那里视觉场景是由实验者操纵的。在这个项目中，我们将结合高密度电生理学、光遗传学和视觉心理物理学来研究速度知觉中运动依赖性变化的神经机制。

Understanding how the brain processes visual images is a fundamental question inneuroscience. As we constantly move around in the world, changes in the visual sceneare largely generated by our own movements. This is particularly true for visualfeatures related to motion and flow, and our perception of speed is known to bealtered by movement. However, visual perception has traditionally been studied instationary subjects, where visual scenes are manipulated by the experimenter. In thisproject, we will investigate the neural mechanisms for movement-dependent changesin speed perception, using a combination of high-density electrophysiological,optogenetics, and visual psychophysics.
