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