Thematik

For most people, vision is the primary source of perception. Quite often, we wonder how it actually works and the answers don't always seem easy. Why is the sky blue? How many megapixels does the human eye have? Can we really see a single photon? What is blindsight? How does the bull see the red cape? How does 3D movie work? This course is aimed at answering many questions of this kind but also at raising some that puzzle researchers today. We will present live demonstrations, illusions and discuss experiments that led to important discoveries in order explain the neural mechanisms of vision in an interesting way. We will also talk about diseases causing loss of visual functions as well as about animal vision. The course begins with an introduction to psychophysical and neurophysiological research methods and a little light physics. Then we follow the path of visual information processing from the photoreceptors to higher visual cortical areas. In the second part, we talk about some of the visual sub-systems including color vision, stereopsis, motion perception and finally visual memory and attention. To conclude the course, we discuss visual illusions that won the latest Best Illusion of the Year Contest.
