It appears that irrespective of the information processing stream in which any given areas are “embedded”, feedback from a particular higher-order cortical area modulates those properties of neurons in the lower area, which play important roles in the information processing in the higher-order areas. Thus, cortical areas in the middle suprasylvian region want to “hear” about the direction of stimulus movement and their feedback signals enhance the magnitude of responses of strongly direction selective cells in the lower areas. By contrast, the pattern/form processing PTV cortex wants to “hear” about the specific properties of stationary/slowly moving stimuli and by feedback signals suppresses the responses of cells in the lower areas such as area 19 or area 17 to fast moving stimuli.
