Studying the visual system (1) The visual system can be (and is) studied using many different techniques. In this course we will consider: Psychophysics What is the level of human visual performance under various different conditions? Anatomy Where are the visual system parts located, and what do they look like? Gross anatomy What do the visual system organs and tissues look like, and how are they connected? Histology What cellular and subcellular structures can be seen under a microscope?

Electrophysiology What is the electrical behavior of neurons, measured with an electrode? Imaging What is the behavior of a large area of the nervous system? Genetics Which genes control visual system development and function, and what do they do? CNV Spring 2009: Vision background
