Abstract: This unit introduces current data about brightness constancy and contrast in visual perception, and shows that data of this kind are a consequence of a principle that holds in all cellular systems. Variations on this principle imply other visual properties, such as edge detection, spatial frequency detection, and pattern-matching properties.
How does a brain build a cognitive code?
This article indicates how competition between afferent data and learned feed-back expectancies can stabilize a developing code by buffering committed populations of detectors against continual erosion by new environmental ... Article Details
Biological competition: Decision rules, pattern formation, and oscillations
Competition solves a universal problem about pattern processing by cellular systems. Competition allows cells to automatically retune their sensitivity to avoid noise and saturation effects. All competitive systems induce ... Article Details
