Three-dimensional organization of otolith-ocular reflexes in rhesus monkeys. III. Responses To translation.
The three-dimensional (3-D) properties of the translational vestibulo-ocular reflexes (translational VORs) during lateral and fore-aft oscillations in complete darkness were studied in rhesus monkeys at frequencies between 0.16 and 25 Hz. In addition, constant velocity off-vertical axis rotations extended the frequency range to 0.02 Hz. During lateral motion, horizontal responses were in phase ...
متن کاملA model that relates canal-ocular to otolith-ocular responses.
Rotation about the vertical stimulates primarily the horizontal semicircular canals and produces compensatory horizontal nystagmus whose slow component velocity response during constant velocity can be approximated as having a simple exponential decay time constant, Tvor. Constant velocity yaw rotation about a horizontal axis stimulates both the horizontal canals and the otolith organs, produci...
متن کاملOcular torsion responses to sinusoidal electrical vestibular stimulation
BACKGROUND Eye movements evoked by electrical vestibular stimulation (EVS) offer potential for diagnosing vestibular dysfunction. However, ocular recording techniques are often too invasive or impractical for routine clinical use. Furthermore, the kinematic nature of the EVS signal is not fully understood in terms of movement sensations. NEW METHOD We apply sinusoidal EVS stimuli varying from...
متن کاملCutaneous reflexes during human gait: electromyographic and kinematic responses to electrical stimulation.
The functions of ipsilateral cutaneous reflexes were studied with short trains of stimuli presented pseudorandomly to the superficial peroneal (SP) and tibial nerves during human gait. Electromyograms (EMGs) of tibialis anterior (TA), soleus, lateral and medial gastrocnemius, vastus lateralis (VL), and biceps femoris (BF) muscle were recorded, together with ankle and knee joint angles. Net refl...
متن کاملTesting the vestibular-ocular reflexes: abnormalities of the otolith contribution in patients with neuro-otological disease.
Conventional vestibular rotation testing with the head centered on the axis stimulates the semicircular canals evoking compensatory eye movements. If the head is placed forwards of the axis in an eccentric position the otoliths are also stimulated by a tangential linear acceleration acting laterally to the skull. In normal subjects the additional otolithic stimulus evokes compensatory eye movem...
