By examining phase-amplitude coupling (PAC) of cortical surface from magnetoencephalographic signals in resting state, we found that PAC is elevated in the occipital lobe as well as the sensorimotor cortex in Parkinson’s disease. This study suggests that PAC detected by MEG will be a biomarker for Parkinson’s disease.
