Sleep Fragmentation in TcMAC21 Mouse Model of Down Syndrome

TcMAC21 mice demonstrated significant sleep fragmentation during the dark phase, potentially reproducing some aspects of sleep disruption in Down syndrome. Interestingly, these findings differed from descriptions of sleep in other DS animal models. Given the high degree of DS gene replication and non-mosaic nature of the TcMAC21 model, it may provide unique insight into the neurologic and anatomic mechanisms of sleep dysfunction in Down syndrome.
