Neural attractor dynamics in object recognition

A widely held theory dating back to Donald Hebb posits neuronal attractor dynamics to underlie the retrieval of objects from long-term memory and the categorization of ambiguous stimuli, but empirical support for this notion had so far pointed more at self-sustained activity than at attractor dynamics per se. Complex perceptual effects modulating memory retrieval, including priming effects, are compatible with both attractor dynamics and...
