How movement and motor practice change the brain in Rett syndrome
Understanding the effects of motor learning in wild-type and Mecp2-deficient mice
This project explores whether motor practice can strengthen brain circuits tied to learning, behavior, and emotions in Rett syndrome models and point to ways to help affected children.

What this research studies
If my child has Rett syndrome, this research looks at how practicing movements changes the brain in mouse models of Rett. Scientists will compare normal and Mecp2-deficient mice as they learn motor tasks and use two-photon calcium imaging to watch activity in motor cortex cells and circuits. They will examine whether improving motor learning alters other behaviors such as social interaction, anxiety, or learning. The goal is to link motor-circuit changes to the cognitive and emotional problems seen in Rett and identify targets for future therapies.
Who could benefit from this research
Good fit: This is preclinical mouse research, so no patients are being enrolled now; future human trials informed by these findings would likely include children with MECP2-related Rett syndrome.
Not a fit: People without MECP2-related Rett syndrome or whose symptoms come from unrelated causes are unlikely to receive direct benefit from this mouse-focused work.
Why it matters
Potential benefit: If successful, the work could point to movement-based therapies or circuit targets that might improve motor, cognitive, or social symptoms in Rett syndrome.
How similar studies have performed: Previous laboratory work, including studies from the PI's lab, has shown motor learning can change circuits and partially improve behaviors in Mecp2-deficient mice, but translation to human benefit remains unproven.
