Fragile X Syndrome (FXS) is a common cause of autism spectrum disorder and intellectual disability (ASD/ID), but the altered neural mechanisms underlying it remain unclear. Here, we investigate the development of the head-direction (HD) system in a rat model of FXS (Fmr1-/y rats) through electrophysiological recordings in the postsubiculum during exploration and sleep. Surprisingly, juvenile...
