A functional role of multiple spatial resolution maps in form perception along the ventral visual pathway

We present a functional model of form pathway in visual cortex based on the predictive recognition scheme, in which feedback image signals predicted from the memory system are compared with the feedforward image signals from the retina. We propose the functional roles of three kinds of spatial resolution maps in predictive perception of object form. The broad resolution map is used to categorize visual image based on the outline of the object and to choose the prediction image in the memory system based on the categorization. The middle resolution map is used for more detailed categorizations and for focusing prediction range. The fine resolution map is used to compare the feedforward image of a part of the object with the image predicted.
