A, schematic outlining the proposed role of neck proprioceptive inputs in contributing to VO neuronal detection thresholds following unilateral labyrinthectomy. B, comparison of population-averaged neuronal thresholds of agonistic VO neurons during whole body rotations (vestibular; blue), body-under-head rotations (neck proprioception; red) and head-on-body rotations (sum; purple) in the normal condition, and within 1 week and >1 week following unilateral labyrinthectomy. Shading indicates s.e.m. VO, vestibular-only.
