Abstract The vestibular system is vital for motor control
and spatial self-motion perception. Afferents from the
otolith organs and the semicircular canals converge with
optokinetic, somatosensory and motor-related signals in the
vestibular nuclei, which are reciprocally interconnected
with the vestibulocerebellar cortex and deep cerebellar
nuclei. Here, we review the properties of the many cell
types in the vestibular nuclei, as well as some fundamental
computations implemented within this brainstem≠cerebel-
lar circuitry. These include the sensorimotor transforma-
tions for reflex generation, the neural computations for
inertial motion estimation, the distinction between active
and passive head movements, as well as the integration of
vestibular and proprioceptive information for body motion
estimation. A common theme in the solution to such
