Deficits in cerebellum-dependent learning and cerebellar morphology in male and female BTBR autism model mice.

Recently, there has been increased interest in the role of the cerebellum in autism spectrum disorders (ASD). To better understand the pathophysiological role of the cerebellum in ASD, it is necessary to have a variety of mouse models that have face validity for cerebellar disruption in humans. Here, we add to the literature on the cerebellum transgenic and induced mouse models of autism with the characterization of the cerebellum in the BTBR T+Itpr3/J (BTBR) inbred mouse strain, which has behavioral phenotypes that are suggestive of ASD in patients.

Sex-dependent influence of postweaning environmental enrichment in Angelman syndrome model mice.

Introduction: Angelman syndrome (AS) is a rare neurodevelopmental disorder caused by mutation or loss of UBE3A and marked by intellectual disability, ataxia, autism-like symptoms, and other atypical behaviors. One route to treatment may lie in the role that environment plays early in postnatal life. Environmental enrichment (EE) is one manipulation that has shown therapeutic potential in preclinical models of many brain disorders, including neurodevelopmental disorders.
