| Abstract | Visual information processing is characterized with two functional aspects; the hierarchical processing and the parallel processing. In thehierarchical processing, representation of information becomes more complex through the course of bottom-up pathway. Importantly, projections between thalamus and cortex or between cortices are reciprocal, and lower order area is controlled by feedback signals from higher order areas. In the parallel processing, visual information is processed by functionally distinct channels, such as magnocellular and parvocellular channels, in parallel. I will talk on our psychological study on the visual masking, metacontrast, and a possible involvement of a spatial-temporal interaction of multiple visual streams, which is partially supported with electrophysiological evidence in V1. |
