Vagus nerve stimulation after practice improves long term skill retention

Stimulating the vagus nerve after practice helped mice develop stronger long-term motor learning, ScienceDaily reported. The research revealed a critical post-practice window during which the brain works to consolidate and lock in newly acquired physical skills. [1]

Researchers linked the improvement to rhythmic changes observed in brain blood vessels following stimulation. According to ScienceDaily, this suggests that body-to-brain signals help prepare brain tissue for lasting neuroplastic change after an activity ends. [1]

The vagus nerve, also known as the tenth cranial nerve, serves as a primary pathway connecting the brain to key organs, including the heart, lungs, and digestive tract. It regulates involuntary parasympathetic functions such as heart rate, breathing, and digestion. [2]

The findings point to broader mechanism behind why some skills lock in quickly while others require extended practice. Scientists hope the discovery of post-practice biological conditions will inform future approaches to learning and neurorehabilitation. [1]
