Circadian rhythm of sleep and wakefulness is a fundamental property of human physiology, which is important for sustaining essential body functions. Brain physiology varies according to the rhythm. In this study, we used ReHo(Regional Homogeneity) method to investigate the diurnal changes of neural activity in normal human brain in resting state.
