Discrete electrocortical predictors of anxiety and anxiety-related treatment response in youth with autism spectrum disorder

There are two established electroencephalogram (EEG) indices that putatively relate to anxiety symptoms: a) the error-related negativity (ERN), which reflects endogenous threat sensitivity, and b) resting-state EEG relative right frontal activity (rRFA), which relates to approach/withdrawal motivation.
