By activating a brain circuit that controls compulsive behavior, researchers in Ann Graybiel‘s lab have shown that they can block compulsive behavior in mice a result that could help researchers develop new treatments for diseases such as obsessive-compulsive disorder (OCD) and Tourette’s syndrome.
A new study from John Gabrieli and colleagues casts doubt on a previous and widely publicized claim that memory training can raise human intelligence. In an attempt to replicate the finding, the MIT researchers confirmed that practice improves performance on the specific task, known as dual n-back; unfortunately, however, the effect did not generalize to other standardized measures of intelligence.
Martha Constantine-Paton and colleagues have studied a mutant mouse strain known as Flailer, showing that it has a defect in a cellular motor that is needed to transport synaptic proteins to their proper sites. Flailer mice also show many behavioral abnormalities, and may be a useful model for studying the neural circuits affected by psychiatric disorders.

This year, the McGovern Institute held its annual retreat at the beautiful Sea Crest Resort in Falmouth, Massachusetts. More than 150 McGovern faculty, staff, researchers, and students attended the 2-day event, which featured 16 talks, a poster session, and a clam bake by the beach.
Pictures from the retreat are posted on our website.
