The human neocortex participates in a wide range of tasks, yet superficially appears to adhere to a relatively uniform six-layered architecture throughout its extent. For that reason, much research has been devoted to characterizing a single "canonical" cortical computation, repeated massively throughout the cortex, with differences between areas presumed to arise from their inputs and outputs rather than from “intrinsic” properties. There is as yet no consensus, however, about what such a canonical computation might be, little evidence that uniform systems can capture abstract and symbolic computation (e.g., language) and little contact between proposals for a single canonical circuit and complexities such as differential gene expression across cortex, or the diversity of neurons and synapse types. Here, we evaluate and synthesize diverse evidence for a different way of thinking about neocortical architecture, which we believe to be more compatible with evolutionary and developmental biology, as well as with the inherent diversity of cortical functions. In this conception, the cortex is composed of an array of reconfigurable computational blocks, each capable of performing a variety of distinct operations, and possibly evolved through duplication and divergence. The computation performed by each block depends on its internal configuration. Area-specific specialization arises as a function of differing configurations of the local logic blocks, area-specific long-range axonal projection patterns and area-specific properties of the input. This view provides a possible framework for integrating detailed knowledge of cortical microcircuitry with computational characterizations. With Adam Marblestone, MIT and Tom Dean, Google

| The stable world problem (see 27 Feb. for readings)
As with many other “problems” in vision and cognitive science, “the binding problem” has been used to label a wide range of tasks of radically different behavioral and computational structure. These include a “hard” version that is currently intractable, a feature-binding variant that is productive routine science and a variable-binding case that is unsolved, but should be solvable. The talk will cover all these and some related problems that seem intractably hard as well as some that are unsolved, but are being approached with current and planned experiments.

| 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.
Contour interaction describes the interference with target recognition that occurs in the presence of nearby flanking edges. As one of the pioneers in this research, Flom distinguished between contour interaction and crowding, in which contributions to spatial interference can derive also from additional factors, such as inaccurate eye movements and attentional processes. In the normal fovea, contour interaction and crowding have a similar magnitude and operate over a similar spatial extent. Both foveal contour interaction and crowding are reduced when the luminance of the stimulus is decreased. Unlike the fovea, the magnitude and extent of contour interaction in peripheral vision are considerably more limited than crowding. Further, peripheral contour interaction and crowding are not affected substantively by target luminance. Indeed, the magnitude and extent of peripheral contour interaction are similar for photopic and scotopic targets. These results suggest that the contributions of specific mechanisms may differ for foveal and peripheral contour interaction and crowding.

Latest revision as of 18:01, 23 April 2015

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, 20 March Today we will continue with Bob Wurtz's review on the stable visual world, getting into:
  • neurons with shifting receptive fields
  • a neural circuit for corollary discharge
  • saccadic suppression
  • trans-saccadic memory
  • attention

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.

Friday, 24 April Brent Parsons will present two papers for discussion:

Bridgeman, B. (2010). How the brain makes the world appear stable. i-Perception, 1(2), 69. pdf

Deubel, H., Koch, C., & Bridgeman, B. (2010). Landmarks facilitate visual space constancy across saccades and during fixation. Vision research, 50(2), 249-259. pdf

I will present a contrasting paper: Fracasso, A., Kaunitz, L., & Melcher, D. (2015). Saccade kinematics modulate perisaccadic perception. Journal of vision, 15(3), 4. pdf
