===Push-pull systems===

The canals are arranged in such a way that each canal on the left side has an almost parallel counterpart on the right side. Each of these three pairs works in a ''push-pull'' fashion: when one canal is stimulated, its corresponding partner on the other side is inhibited, and vice versa.{{citation needed|date=May 2022}}

This push-pull system makes it possible to sense all directions of rotation: while the ''right horizontal canal'' gets stimulated during head rotations to the right (Fig 2), the ''left horizontal canal'' gets stimulated (and thus predominantly signals) by head rotations to the left.

Vertical canals are coupled in a crossed fashion, i.e. stimulations that are excitatory for an anterior canal are also inhibitory for the contralateral posterior, and vice versa.
