The primary motor cortex (M1) is crucial for motor skill learning. We examined its role in interleaved practice, which enhances retention (vs. repetitive practice) through M1-dependent consolidation. We hypothesized that cathodal transcranial direct current stimulation (ctDCS) to M1 would disrupt retention. We found that ctDCS reduced retention…

Background: Laparoscopic cholecystectomy (LC) is one of the most frequently performed surgical procedures worldwide with occasional serious complications, including bile duct injuries, that may reflect surgeon misperception, rather than errors of skill and knowledge. Intraoperative cholangiography (IOC) is an imaging procedure that may prevent or…

Objective: Measurement tools for children's foundational skills provide important insights towards the developmental mechanisms of these domains. This study examines the structure of sensorimotor, visuospatial processing (VP), executive function (EF) skills and their interrelationship. The NEPSY is a widely-used neuropsychological instrument, but…
