The wave in the perilymph moves away from the footplate and towards the helicotrema.

He used glass slides, razor blades, and an elastic membrane to represent the helicotrema.

This area is called the helicotrema.

Higher frequencies do not propagate to the helicotrema, due to the stiffness-mediated tonotopy.

The far end of the structure has a hole between the two channels called the helicotrema that equalizes slowly varying pressures in the two channels.

At the apical end of the cochlea, at an opening known as the helicotrema, the scala vestibuli merges with the scala tympani.

The work has also been performed and broadcast at Tate Britain (UK) and Helicotrema Festival (Italy)

The helicotrema is sometimes referred to as "Breschet's hiatus", a passageway that connects the scala tympani and scala vestibuli at the top of the cochlea.

It is separated from the scala media by Reissner's membrane and extends from the vestibule of the ear to the helicotrema where it joins scala tympani.

For very low frequencies (below 20 Hz), the waves propagate along the complete route of the cochlea - differentially up scala vestibuli and scala tympani all the way to the helicotrema.

Near the summit of the cochlea the lamina ends in a hook-shaped process, the hamulus laminae spiralis; this assists in forming the boundary of a small opening, the helicotrema, through which the two scalae communicate with each other.

In human anatomy of the ear, the extremities of the ductus cochlearis are closed; the upper is termed the lagena and is attached to the cupula at the upper part of the helicotrema; the lower is lodged in the recessus cochlearis of the vestibule.
