Well over half of multiple sclerosis patients report problems with their vision, but until recently we had little idea of what was happening to their visual systems in the disease. Now, by combining visual psychophysics with clinical tests and the recent developments in nuclear magnetic resonance imagining, we are learning a great deal about the nature of the damage to the visual pathways. This research also helps us to understand the functioning of the normal visual system. Other research involves the experimental investigation of visual attention and the recognition of real-world objects from vision. Although data from human subjects is central, computers play a crucial role in the generation of plausible models of psychological processes.
Much interest is with the more recent neural network approach to understanding perceptual processes.
The guiding assumption here is that attempting to build an artificial brain can lead to important insights about how real brains operate.
