Drs. Amelie Baud and Sandra Sanchez-Roige presented at the 2019 World Congress of Psychiatric Genetics in Los Angeles, CA earlier this week.

Dr. Baud presented a talk entitled “Genetic effects from the social environment” in which she presented evidence that mouse and rat behaviours relevant to psychiatric disorders can be affected not only by the animal’s own genes but also by genes of cage mates. She also illustrated how such “indirect genetic effects” can be leveraged to dissect the mechanisms of social effects, more precisely to identify traits of social partners
