Shared Neural and Computational Anomaly in Autism Mice
- A study on autism mouse models explores the shared neural and computational anomalies observed in autism spectrum disorder (ASD).
- Autism spectrum disorder is characterized by social communication difficulties, repetitive behaviors, and sensory sensitivities.
- Individuals with ASD often exhibit inflexible updating of internal models, affecting decision-making processes.
- The study focused on mice with mutations in Fmr1, Cntnap2, and Shank3B genes linked to ASD, revealing common behavioral phenotypes.
- ASD mouse models displayed reduced updating of prior expectations, resembling findings in human ASD populations.
- Neurophysiological data showed reorganization of neural computations, with a shift in prior information representation from sensory to frontal areas.
- Frontal cortical neurons in ASD-model mice exhibited heightened sensitivity to prediction errors, influencing decision-making processes.
- The study's findings align with predictive coding theories of ASD, emphasizing an imbalance in sensory prediction signals.
- Distinct genetic perturbations can lead to common computational anomalies, suggesting convergent disruptions in cortical processing in ASD.
- The research offers potential therapeutic targets for restoring cognitive flexibility in individuals with ASD.
