The left vocal fold opened earlier and a robust mucosal wave is visible on the left vocal fold. (B) Condition L SLN level 4 and R SLN level 4. Mucosal waves are equally robust and symmetric. (C) Condition L SLN 0, R SLN 4, the right vocal fold opened earlier and a robust mucosal wave is present on the right vocal fold surface. (See text for full discussion.)
