Classic psychedelics have re-emerged as compelling probes of neural plasticity, raising interest in their potential relevance for behavioral and circuit-level features associated with autism spectrum disorder (ASD). Although only a limited number of studies have examined these compounds in validated animal models of ASD, a growing body of preclinical work has investigated their effects on...
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,...
