%X People can efficiently recognize an object even under some extremely poor viewing conditions.Such efficient visual processing depends on both bottom-up input and top-down regulations.The present study used a novel illusory detection paradigm to investigate the neural network involved in top-down letter processing.This paradigm required participants to detect letters in pure noise images that actually contained no letters.By using of psychophysiological interaction(PPI) analysis,it revealed that some regions...
