POSTER PRESENTATION Open Access Fine temporal structure of neural synchronization

While neural synchronization is widely observed in neu-roscience, neural oscillations are rarely in perfect syn-chrony and go in and out of phase in time. Since this synchrony is not perfect, the same synchrony strength may be achieved with markedly different temporal pat-terns of activity (roughly speaking oscillations may go out of the phase-locked state for many short episodes or few long episodes). Recent developments in the time-series analysis allowed for the investigation of the tem-poral variations of phase-locking with a high temporal resolution [1]. Provided that there is some average level of phase-locking is present, one can follow oscillations from cycle to cycle and to observe if the phase differ-ence is close to the preferred phase lag or not [1].
