 Evidence using EEG and MEG suggests that stimulus repetition in humans results in increased synchrony between distinct cortical regions, often the same regions that show reduced local neural activity (see repetition suppression below).In one study, the timing of this across-region synchronization predicted the amount of behavioral facilitation seen with repetition priming, suggestive of a close link between synchrony and behavior.This theory suggests that repetition priming is a result of binding the initial stimulus directly to the response while bypassing the intervening layers of computation.
