Deficiency in certain brain proteins shown to promote compulsive behavior
by Julia Reichelt, Rheinland-Pfälzische Technische Universität Kaiserslautern-Landau Credit: Claudia Knorr/FMP Our behavior is controlled through neural circuits in the brain. Molecular disturbances can lead to stereotypical behavior, as seen in neuropsychiatric disorders such as obsessive-compulsive and autism spectrum disorders. A research team has now demonstrated that the absence of two proteins, Intersectin1 and Intersectin2, in mice leads...
