Fragile X syndrome (FXS) is an inherited form of intellectual disability and autism. Among other symptoms, FXS patients demonstrate abnormalities in sensory processing and communication. Clinical, behavioral, and electrophysiological studies consistently show auditory hypersensitivity in humans with FXS. Consistent with observations in humans, the Fmr1 KO(More)
This study provides the first description of auditory cortical processing in a mouse model of Fragile X Syndrome (FXS). FXS is a genetic cause of intellectual impairment and is an autism spectrum disorder. Human studies with auditory evoked potentials indicate that FXS is associated with abnormal auditory processing. The Fmr1 knock-out (KO) mouse is a(More)
Fragile X Syndrome (FXS) is the most common inherited form of intellectual disability, with behaviors characteristic of autism. Symptoms include abnormal social behavior, repetitive behavior, communication disorders, and seizures. Many symptoms of FXS have been replicated in the Fmr1 knockout (KO) mice. Whether Fmr1 KO mice exhibit vocal communication(More)
Fragile X Syndrome (FXS) is the most common single-gene inherited form of intellectual disability with behaviors characteristic of autism. People with FXS display childhood seizures, hyperactivity, anxiety, developmental delay, attention deficits, and visual-spatial memory impairment, as well as a propensity for obsessive-compulsive disorder. Several of(More)
Fragile X Syndrome (FXS), a neurodevelopmental disorder, is the most prevalent single-gene cause of autism spectrum disorder. Autism has been associated with impaired auditory processing, abnormalities in the auditory brainstem response (ABR), and reduced cell number and size in the auditory brainstem nuclei. FXS is characterized by elevated cortical(More)
Many animals produce long sequences of vocalizations best described as " songs. " In some animals, such as crickets and frogs, these songs are relatively simple and repetitive chirps or trills. However, animals as diverse as whales, bats, birds and even the humble mice considered here produce intricate and complex songs. These songs are worthy of study in(More)
Caspase-3 is a cysteine protease that is most commonly associated with cell death. Recent studies have shown additional roles in mediating cell differentiation, cell proliferation and development of cell morphology. We investigated the role of caspase-3 in the development of chick auditory brainstem nuclei during embryogenesis. Immunofluorescence from(More)
