Within approximately 10 seconds of achieving constant motion, the endolymph catches up with the movement of the duct and the cupula is no longer affected, stopping the sensation of acceleration.

Endolymph has a high positive potential ( 80 120 mV in the cochlea ), relative to other nearby fluids such as perilymph, due to its high concentration of positively charged ions.
43.
Beginning in the fifth week of development, the auditory vesicle also gives rise to the cochlear duct, which contains the spiral organ of Corti and the endolymph that accumulates in the membranous labyrinth.
44.
Due to its location, the basilar membrane places the hair cells in a position where they are adjacent to both the endolymph and the perilymph, which is a precondition of hair cell function.
45.
This gene is expressed in fetal cochlea and many other tissues, and is thought to be involved in the development and maintenance of the inner ear or the contents of the perilymph and endolymph.
46.
Otolithic organs have a thick, heavy gelatin membrane that, due to inertia ( like endolymph ), lags behind and continues ahead past the macula it overlays, bending and activating the contained cilia.
47.
The alcohol apparently causes the ampullary cupula in the semicircular canal to become lighter than the surrounding fluid ( endolymph ), which causes the system to become sensitive to gravity in addition to rotational acceleration.
48.
The perilymph that is found in the scala tympani has a low potassium concentration, whereas the endolymph found in the scala media has a high potassium concentration and an electrical potential of about 80 millivolts compared to the perilymph.
49.
Because the hair cells are at a negative potential of about-50 mV, the potential difference from endolymph to hair cell is on the order of 150 mV, which is the largest electrical potential difference found in the body.

Endolymph naturally flows into the endolymphatic sac situated between the skull and the brain, but with LVAS, it may reverse direction and flow backwards into parts of the inner ear involving hearing and balance causing damage to the inner ear.
