We have previously shown differential effects of stimulus familiarity on the repetition‐related responses in right fusiform cortex to both faces and symbols. Repetition of familiar stimuli produced a response decrease, whereas repetition of unfamiliar stimuli produced a response increase. In the present experiment, we used words and nonwords as the familiar and unfamiliar stimuli respectively. In this case, the only fusiform region showing the familiarity‐by‐repetition interaction was in anterior left fusiform. This left‐lateralisation of the fusiform interaction is consistent with our hypothesis that these repetition‐related effects occur in the same regions responsible for perceptual recognition of familiar stimuli.
