Individual differences in sensory sensitivity: Further lessons from an Autism model.

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.

Predictable enriched environment prevents development of hyper-emotionality in the VPA rat model of autism.

Understanding the effects of environmental stimulation in autism can improve therapeutic interventions against debilitating sensory overload, social withdrawal, fear and anxiety. Here, we evaluate the role of environmental predictability on behavior and protein expression, and inter-individual differences, in the valproic acid (VPA) model of autism. Male rats embryonically exposed (E11.

General developmental health in the VPA-rat model of autism.

Autism is a neurodevelopmental condition diagnosed by impaired social interaction, abnormal communication and, stereotyped behaviors. While post-mortem and imaging studies have provided good insights into the neurobiological symptomology of autism, animal models can be used to study the neuroanatomical, neurophysiological and molecular mediators in more detail and in a more controlled environment. The valproic acid (VPA) rat model is an environmentally triggered model with strong construct and clinical validity.
