In rodents, valproic acid (VPA) exposure in utero is widely used to an ASD model (Shin, 2015) because of its obvious surface fidelity. VPA has been reported as a risk factor of ASD in human clinical studies (Christensen, 2013). We have reported VPA exposed ASD model in non-human primate, common marmoset (Callithrix jacchus) (Yasue, 2015). Here we show brain structural and behavioral phenotypes in early developmental stage of this model. By using high-resolution diffusion tensor imaging (DTI) of neonatal marmosets brain, we found the size of the anterior commissure of ASD model marmosets (n=7) is significantly smaller than that of unexposed (UE) marmosets (n=9) (P2 day, p < 0.05). The kinship vocal communications in the family with ASD model child were longitudinally recorded. There were significant differences in call-use between VPA and UE families. In VPA families, frequency of social isolation call “phee” was increased, while “trill” call was decreased (P90 day, 9 VPA exposed, and 7 UE). These results suggested that VPA model marmosets have a risk of communication deficits at neonate, which is manifested by family social event, e.g. weaning., 12th International “Stress and Behavior” Society Regional Conference (Asia)}, title = {Atypical Behavioral and Neural Phenotypes in a Common Marmoset Model of Autism Spectrum Disorders}, year = {2017} }
