The definition of phase-locking value(PLV) in python-mne is correct?

WebbIn their original paper, Lachaux et al (1999) defined the PLV as a time-dependent connectivity measured tailored to study evoked activity. The idea behind their definition is that the stimulus resets the phase of the neural oscillators so that sig-nals connected in a given time should have a stable phase-difference along trials.
