Vagus nerve may help turn practice into lasting motor memories, study finds

Repetition alone cannot guarantee learning; newly practised motor skills require post-training memory consolidation.

Tohoku University researchers demonstrated that stimulating the vagus nerve in mice immediately after training significantly enhances long-term motor learning over subsequent days.

The treatment did not improve immediate performance, proving Vagus Nerve Stimulation specifically acts on memory stabilisation rather than real-time execution.

These findings highlight a critical role for body-to-brain communication - potentially driven by changes in active brain tissue - in solidifying physical memories long after practice.
