Repetition probability does not affect fMRI repetition suppression for objects.
Previously several functional magnetic resonance imaging (fMRI) studies point toward the role of perceptual expectations in determining adaptation or repetition suppression (RS) in humans. These studies showed that the probability of repetitions of faces within a block influences the magnitude of adaptation in face-related areas of the human brain (Summerfield et al., 2008). However, a current ...
متن کاملStimulus repetition probability does not affect repetition suppression in macaque inferior temporal cortex.
Recent human functional magnetic resonance imaging studies (Summerfield C, Trittschuh EH, Monti JM, Mesulam MM, Egner T. 2008. Neural repetition suppression reflects fulfilled perceptual expectations. Nat Neurosci. 11:1004-1006.) showed that adaptation or repetition suppression is affected by contextual factors related to perceptual expectations, suggesting that adaptation results from a fulfil...
متن کاملWhen does repetition suppression depend on repetition probability?
It has been shown recently that the probability of stimulus repetitions (Prep) determines the degree of repetition suppression (RS): the repetition-related decrease of the fMRI signal (fMRI adaptation, fMRIa) was larger for faces in the fusiform face area (FFA) in blocks with high when compared to low repetition probabilities (Summerfield et al., 2008). This suggests that higher-order contextua...
متن کاملRepetition suppression for pitch using fMRI
Perception of communication signals in noisy environments is a critical function of the auditory system. Our ability to perceive a communication signal in a noisy environment is aided by certain properties of the background noise: hearing thresholds in co-modulated noise are lower than in unmodulated noise. This effect is called “co-modulation masking release”. It is hypothesized that the fluct...
متن کاملExpertise reduces neural cost but does not modulate repetition suppression
The extent to which repetition suppression is modulated by expertise is currently unknown. We used event-related fMRI to test whether architecture students would respond faster to buildings and would exhibit stronger repetition suppression in the fusiform gyrus (FG) and parahippocampa cortex (PHC) than students from other disciplines. Behaviorally, we found shorter response latencies with targe...
