 My research interests

I am trying to understand how vision works. I think that detection and recognition of patterns are the most essential in it.
There is much more information in the visible world than we are able or need to use. An important function of any visual system is to select the important and ignore irrelevant aspects of the world. The mechanisms that mediate the selection are named “attention”. Many of my studies are in some way related to that. Another frequent keyword is “crowding” - deterioration of perception when several objects are located close to each other, usually in peripheral vision. Then, our visual system "selects" some kind of information too, and loses other.
My methods are psychophysical experiments and mathematical or computational modeling. But I think that single-cell neurobiology is equally interesting.
When could we say that we have understood vision? I have suggested that when we can build a machine or write a computer program that could orient in the visual world as effectively as humans, monkeys and other living creatures. Can you?
