A Measure of Phase Locking of Cortico-cortical Brain Rhythms in Meditation EEG
January 1, 2016 Laxmi Shaw, A. Routray
Phase synchrony analysis of EEG signals from 23 meditators during meditation reveals that an Improved Phase Locking Value (IPLV) method outperforms the standard Phase Locking Value (PLV) in detecting neural synchrony. Neural synchrony modulated the EEG signals independently, offering a better interpretation of functional connectivity between cortical areas during meditation. The work uses phase synchrony to study simultaneous peaks and valleys in EEG activity, capturing transient spectral perturbations across different brain regions.
