Impaired formation and updating of internal predictive models in a rat model of Fragile X Syndrome

David Walker Gauthier, Ethan Hong, Noelle James, Benjamin D. Auerbach

This study uses a probabilistic oddball task to show that Fmr1 KO rats have impaired predictive processing, failing to adapt to changing statistics and overweighting immediate sensory input.

Disrupted Developmental Trajectory of Ultrasonic Vocalizations in a Rat Model of Fragile X Syndrome

David Walker Gauthier, Arjun Vaidya, Benjamin D. Auerbach

This study examines how Fmr1 mutation affects the developmental trajectory of ultrasonic vocalizations in rats, finding reduced call numbers and delayed syntactic complexity in Fmr1 knockout pups.

Stable, Variable, Encoding: Distinct Roles of SST, VIP, and EXC Neurons in Visual Novelty Processing

Karni Lev Bar-Or, Vyshnavi Sankaran Krishnan, David Walker Gauthier

The paper examines how different neuron types encode visual novelty over time, finding that SST neurons maintain stable representations while VIP neurons show flexible encoding depending on novelty type.

Altered auditory feature discrimination in a rat model of Fragile X Syndrome

David Walker Gauthier, Noelle James, Benjamin D. Auerbach

This study investigates altered frequency discrimination in Fmr1 KO rats, linking cortical hyperactivity and tuning width to auditory processing deficits in FXS.
