Abstract The temporal processing in the encoding of
head rotation was investigated by comparing the dynamics
of vestibular nuclei neurons with those of the regularly and
irregularly firing semicircular canal afferents in alert
rhesus monkeys. During earth-vertical axis rotations,
neurons without eye movement sensitivity differed in
their response dynamics from both regularly and irregu-
larly firing semicircular canal afferents. At high frequen-
cies, central responses increased in sensitivity and
maintained phase leads of nearly 30 relative to head
velocity. These persistent high-frequency phase leads
resembled those of irregularly firing (but not regularly
