Abstract
Repetitions of a sensory event elicit lower levels of brain activity than its initial presentation ("repetition suppression," RS). According to one view, RS depends on the biophysics of neuronal discharge, and is thus an automatic consequence of stimulus processing ("fatigue" model). Another account suggests that RS depends on the statistical structure of the environment, and occurs when repeated stimuli are less surprising than novel stimuli ("surprise reduction" model). In support of the latter view, functional magnetic resonance imaging studies have shown that RS is modulated by the local p
