VS298: Visual Perception and its Neural Substrates
Psychophysical studies have taught us much about the nature of visual perception, suggesting the existence of certain neural mechanisms and representations. On the other hand, neuroscience has taught us much about neural coding properties and about the signal transformations occurring at various stages of the system. And yet there are surprisingly few findings that link these branches of investigation. The goal of this seminar is to examine the literature from both sides, with an eye towards bridging the gap. The work of physiologists (e.g., Victor Lamme and Rüdiger von der Heydt) and psychophysicists (e.g., Ken Nakayama and Patrick Cavanaugh) will be studied in depth.
The seminar will meet weekly. Coursework will consist of presenting analyses of readings in class and/or participation in a collaborative computational modeling project to simulate the neural phenomena we will be studying.

|Friday, Jan. 23||Introduction|
|Friday, Feb. 13||The V1 classical receptive field
|Friday, Feb. 20||Fine structure for parallel processing in visual cortex
|Friday, Feb. 27 (class postponed till 6 March)||The stable world problem
|Friday, 6 March [postponed till the next week]||The stable world problem (see 27 Feb. for readings)|
|Friday, 20 March||Today we will continue with Bob Wurtz's review on the stable visual world, getting into:
As last week, in the second hour we will discuss how to design (and actually implement here at Berkeley) experiments suggested by the material from the first hour.
|Friday, 3 April||We continue with stable world perception, focusing on Wurtz review article. I will report on my correspondence with Marc Sommer, who did a lot with shifting RFs in physiology experiments.|
|Friday, 10 April||We will begin our focus on visual attention, with some neat videos to get things started.|
|Friday, 17 April||Bruno Olshausen will lead discussion of dynamic routing and visual attention. This is a key research topic in Bruno's lab, so both past work and ideas for future modeling/experiments will be on the menu.
His 1993 publication: "A Neurobiological Model of Visual Attention and Invariant Pattern Recognition Based on Dynamic Routing of Information" is background ready. Please check out this classic paper.
