abstract = {The resting human brain cycles through distinct states that
can be analyzed using microstate analysis and
electroencephalography(EEG) data. This approach classifies
multichannel EEG data into spontaneously interchanging
microstatesbased on topographic features. These microstates
may be valuable biomarkers in neurodegenerative
diseasessince they reflect the resting brain’s state.
However, microstates do not provide information about the
active neuralnetworks during the resting state. This article
presents an alternative and complementary method for
analyzingresting-stateEEG data and demonstrates its
reproducibility and reliability. This method considers
cerebral connectivitystates defined by phase synchronization
and measured using the corrected imaginary
phase-lockingvalue (ciPLV)based on source-reconstructedEEG
recordings. We analyzed resting-stateEEG data from young,
healthy participantsacquired on five consecutive days before
and after a motor task. We show that our data reproduce
microstatespreviously reported. Further, we reveal four
stable topographic patterns over the multiple recording
sessions in thesource connectivity space. While the
classical microstates were unaffected by a preceding motor
task, the connectivitystates were altered, reflecting the
suppression of frontal activity in the post-movementresting
state.},
