When sound waves hit your eardrum, they are converted to vibrational signals, which are then transmitted through the inner ear via three small bones. The vestibular nerve carries the signal to the brain for interpretation. The spinning or dizzy sensation associated with benign paroxysmal positional vertigo (
BPPV) is caused by the buildup of calcium particles in the canals of the ear. Depending on the origin of the sensation, determines the type of vertigo it is. Otolith organs, or other structures in your ear monitor head movement, and position relative to gravity. These organs contain crystals which sense gravitational fields. When these crystals dislodge, they can cause the semicircular canal of the ear to become hypersensitive to position changes, making you feel dizzy. For
