Short latency linear vestibular sensory evoked potentials (VsEPs) provide a means to
objectively and directly assess the function of gravity receptors in mammals and birds. The
importance of this functional measure is illustrated by its use in studies of the genetic basis
of vestibular function and disease. Head motion is the stimulus for the VsEP. In the bird, it
has been established that neurons mediating the linear VsEP respond collectively to the rate
of change in linear acceleration during head movement (ie jerk) rather than peak …
