How Brains Filter Familiar Stimuli: The Negative-Image Model for Habituation

Ramaswami proposes a conceptually simple mechanism by which nervous systems may identify and filter familiar or predicted stimuli. He further discusses the importance of this mechanism for higher cognitive functions such as attention and learning, as well as its relevance to autism spectrum disorders.
