Intermittent dynamics underlying the intrinsic fluctuations of the collective synchronization patterns in electrocortical activity
(2007) In Physical Review E (Statistical, Nonlinear, and Soft Matter Physics) 76(1).- Abstract
We investigate patterns of collective phase synchronization in brain activity in awake, resting humans with eyes closed. The alpha range of human electroencephalographic activity is characterized by ever-changing patterns, with strong fluctuations in both time and overall level of phase synchronization. The correlations of these patterns are reflected in power-law scaling of these properties. We present evidence that the dynamics underlying this fluctuation is type-I intermittency. We present a model study illustrating that the scaling property and the collective intermittent dynamics are emergent features of globally coupled phase oscillators near the critical point of entering global frequency locking.
