Practice may teach the brain a new movement, but what happens immediately afterward could determine whether that skill lasts.
Scientists have long known that repetition alone does not guarantee learning. A newly practiced movement must be stabilized through memory consolidation, a process that continues after training ends. New research in mice suggests that signals arriving from the body can help create the conditions needed for that transformation.
Researchers at Tohoku University who specialize in super-network brain physiology found that stimulating the vagus nerve after training produced stronger motor learning over the following days. The results reveal a potentially important role for communication between the internal organs and the brain in shaping long-term learning.
