•Repetitive tactile stimulation improves somatosensory spatial and temporal perception.•The same intervention also modifies cortical sensorimotor interactions.•These changes are likely due to an increased effectiveness of cortical inhibition. High frequency repetitive somatosensory stimulation (HF-R...
