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

了解大脑如何处理视觉图像是神经科学中的一个基本问题。当我们在世界上不断移动时，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，并且我们对速度的感知已知会因运动而改变。然而，视觉感知传统上是在静止的受试者中研究的，其中视觉场景由实验者操纵。在这个项目中，我们将研究运动依赖性变化的神经机制的速度知觉，使用高密度电生理学，光遗传学和视觉心理物理学的组合。
