Social Bayes: Using Bayesian Modeling to Study Autistic Trait-Related Differences in Social Cognition.

Background: The autistic spectrum is characterized by profound impairments of social interaction. The exact subpersonal processes, however, that underlie the observable lack of social reciprocity are still a matter of substantial controversy. Recently, it has been suggested that the autistic spectrum might be characterized by alterations of the brain's inference about the causes of socially relevant sensory signals.

However, it is unclear at what level of processing such trait-related alterations may occur.

An Obesity-Predisposing Variant of the FTO Gene Regulates D2R-Dependent Reward Learning.

Variations in the fat mass and obesity-associated (FTO) gene are linked to obesity. However, the underlying neurobiological mechanisms by which these genetic variants influence obesity, behavior, and brain are unknown. Given that Fto regulates D2/3R signaling in mice, we tested in humans whether variants in FTO would interact with a variant in the ANKK1 gene, which alters D2R signaling and is also associated with obesity.
