From: Adaptive brain activity changes during tongue movement with palatal coverage from fMRI data

Change in tongue motor dexterity and difficulty of tongue movement (n = 27). Error bars represent standard deviation. Day 0: pre-insertion; Day 1: immediately after insertion; Day 3: 3 days after insertion; Day 7: 7 days after insertion. VAS: visual analogue scale. *P < 0.05, **P < 0.01, ***P < 0.005, **** P < 0.001.
