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

ABSTRACT: Atypical sensory processing, particularly in the auditory domain, is one of the most common and quality-of-life affecting symptoms seen in autism spectrum disorders (ASD). Fragile X Syndrome (FXS) is the leading inherited cause of ASD and a majority of FXS individuals present with auditory processing alterations. While auditory hypersensitivity is a common phenotype observed in FXS and Fmr1 KO rodent models, it is important to consider other auditory coding impairments that could contribute to sound processing difficulties and disrupted language comprehension in FXS. We have shown previously that a Fmr1 knockout (KO) rat model of FXS exhibits heightened sound sensitivity that coincided with abnormal perceptual integration of sound bandwidth, indicative of altered spectral pro
