abstract = {Our sensory system is able to build a unified perception of the world, which although
rich, is limited and inaccurate. Sometimes, features from different objects
are erroneously combined. At the neural level, the role of the parietal cortex in
feature integration is well-known. However, the brain dynamics underlying correct
and incorrect feature integration are less clear. To explore the temporal dynamics
of feature integration, we studied the modulation of different frequency
bands in trials in which feature integration was correct or incorrect. Participants
responded to the color of a shape target, surrounded by distractors. A calibration
procedure ensured that accuracy was around 70% in each participant. To explore
the role of expectancy in feature integration, we introduced an unexpected
feature to the target in the last blocks of trials. Results demonstrated the contribution
of several frequency bands to feature integration. Alpha and beta power
was reduced for hits compared to illusions. Moreover, gamma power was overall
larger during the experiment for participants who were aware of the unexpected
target presented during the last blocks of trials (as compared to unaware participants).
These results demonstrate that feature integration is a complex process
that can go wrong at different stages of information processing and is influenced
by top-down expectancies.},
