Phase Resetting on Scalp EEG, Study on Its Synchrony and Distribution
A 64 electrode cap was used to record the EEG from 6 subjects. The Hilbert transform was used to estimate the analytic amplitude and analytic frequency. Phase resetting were identified by spikes on the temporal differences of successive unwrapped analytic phase value. Evidence was acquired of global phase resetting and re-synchronization that is necessary for the spatial-temporal pattern emergence. Phase resetting were clustered in time and this is evidence that the channels are not completely independent. The repetition rates of the phase resetting were proportional to the filter bandwidth by a factor close to 0.641 as predicted by Rice.
