The vestibular system contributes to a wide range of
functions, from postural and oculomotor reflexes to spatial
representation and cognition.13 Karnath and Dieterich2 found
that healthy subjects may show symptoms similar to UN
after unilateral vestibular stimulation, such as the deviation
of the eyes and/or head to the ipsilateral side. Both spatial
neglect and vestibular processing at the cortical level show
dominance in the right hemisphere and involve common
brain areas
