Fragile X Syndrome (FXS) is the most common inherited intellectual disability and a leading monogenic cause of autism spectrum disorder (ASD). As a synaptic disorder, FXS involves the loss of Fragile X messenger ribonucleoprotein 1 (FMRP), leading to abnormal dendrite development and immature dendritic spines. Serotonergic signaling, essential for neuronal development and circuit remodeling, has been implicated in ASD and related conditions, including FXS, raising the possibility that serotonergic modulation could ameliorate neurodevelopmental impairments. This study investigated the therapeutic potential of psilocybin, a serotonergic compound, in the validated Fmr1- Show less
