In this commentary, we join Ward (this issue) in the usefulness of conceptualizing neural output in terms of signal and noise relationships, to create the missing links between neural, behavioral and subjective sensory sensitivity. We draw from our work in the Intense World Theory of Autism and the valproic acid rodent model, to complement the discussion with the consideration of developmental time and function of the system, for a neural output to serve as a predictor of atypical outcome in sensory sensitivity, and guide personalized therapies.
