Durations of quasi-stable EEG phase synchrony reflect the amount of visual information

Results Among the nine studied frequency bands, we found that the durations were systematically related to AR in the beta EEG frequency band (~ 20 Hz). Conclusions The durations of intervals of synchronized activity depend on stimulus ambiguity. Since the amount of stimulus information co-varied with stimulus ambiguity, the results are consistent with the view that durations of quasi-stable intervals manifest the amount of stimulus information.
