A new theory clarifies computation in the secondary visual area of primates

No theory has explained clearly the properties of the secondary visual area, which is considered to be an important part of the primate visual system. We have developed a new theory in which the secondary visual area may acquire complex computational capabilities by learning the statistical properties of natural images that are normally projected onto the eyes. Our study takes an important step toward understanding of the entire visual system and may advance technologies of artificial intelligence.
