Time processing requires the estimation of events' duration per se, but also seems to trigger attentional and memory processes. (MEG) activity was recorded in fourteen healthy right-handed volunteers. We report an increase of gamma-band oscillations over right fronto-central and parietal regions when subjects are prompted to attend to duration. Our results support the hypothesis that the right fronto-parietal network observed repeatedly in time estimation imaging studies is indeed involved in attentional control rather than stimulus processing. Moreover, they underline the supramodal property of time dimension that goes beyond purely perceptive features.
