Parents, Peers, and Musical Play: Integrated Parent-Child Music Class Program Supports Community Participation and Well-Being for Families of Children With and Without Autism Spectrum Disorder.

Opportunities for meaningful community participation may influence the development and well-being of individuals with autism spectrum disorder (ASD) and their families as well as impact how community members perceive and understand ASD. In the current study, we aimed to understand how a parent-child integrated music class program could be used to promote community participation and family well-being. Caregivers of preschoolers (2-5 years of age) with ASD and those of peer children with typical development (TD) were interviewed about their participation in a parent-child integrated music class program.

Social motor coordination during adult-child interactions.

Social motor coordination (SMC) pertains to the timing of contingent movements during social interactions and is of high relevance for successful social and musical interactions. Semi-automated, objective methods are increasingly being used to analyze SMC, though it is unclear if these methods are feasible in naturalistic settings with young children. The purpose of the current preliminary study was to explore SMC in adult-child dyads during semi-structured social interactions.

Neuromodulation of olfactory sensitivity in the peripheral olfactory organs of the American cockroach, Periplaneta americana.

Olfactory sensitivity exhibits daily fluctuations. Several studies have suggested that the olfactory system in insects is modulated by both biogenic amines and neuropeptides. However, molecular and neural mechanisms underlying olfactory modulation in the periphery remain unclear since neuronal circuits regulating olfactory sensitivity have not been identified.

Genetic background modulates phenotypes of serotonin transporter Ala56 knock-in mice.

Background: Previously, we identified multiple, rare serotonin (5-HT) transporter (SERT) variants in children with autism spectrum disorder (ASD). Although in our study the SERT Ala56 variant was over-transmitted to ASD probands, it was also seen in some unaffected individuals, suggesting that associated ASD risk is influenced by the epistatic effects of other genetic variation. Subsequently, we established that mice expressing the SERT Ala56 variant on a 129S6/S4 genetic background display multiple biochemical, physiological and behavioral changes, including hyperserotonemia, altered 5-HT receptor sensitivity, and altered social, communication, and repetitive behavior.
