•Scale-free brain dynamics in sensory regions exhibit a time-dependent spectral exponent in response to naturalistic inputs•This time-dependent spectral exponent positively correlates with time-varying inter-subject correlation in visual and auditory regions•The relative Rest-to-Movie SD change in t...
