Aperiodic spectral slope tracks the effects of brain state on saliency responses in the human auditory cortex

Abstract Alteration of responses to salient stimuli occurs in a wide range of brain disorders and may be rooted in pathophysiological brain state dynamics. Specifically, tonic and phasic modes of activity in the reticular activating system (RAS) influence, and are influenced by, salient stimuli, res...
