When the fluid moves, nerve endings in the canal are excited and send a message to the brain that the head is moving, even though it isn’t. However, the crystals do move with gravity, thereby moving the fluid when it normally would be still. Hain.įluid in the semicircular canals does not normally react to gravity.

Otoconia migrate from the utricle, most commonly settling in the posterior semicircular canal (shown), or more rarely in the anterior or horizontal semicircular canals.
