2035, 2004; 10.1152/jn.00047.2004. A gaze-stabilization reflex that
has been conserved throughout evolution is the rotational vestibu-
loocular reflex (RVOR), which keeps images stable on the entire
retina during head rotation. An ethological newer reflex, the transla-
tional or linear VOR (TVOR), provides fast foveal image stabilization
during linear motion. Whereas the sensorimotor processing has been
extensively studied in the RVOR, much less is currently known about
the neural organization of the TVOR. Here we summarize the com-
putational problems faced by the system and the potential solutions
that might be used by brain stem and cerebellar neurons participating
in the VORs. First and foremost, recent experimental and theoretical
evidence has shown that, contrary to popular beliefs, the sensory
