Short-duration galvanic vestibular stimulation evokes prolonged balance responses.
The application of galvanic vestibular stimulation (GVS) evokes distinct responses in lower limb muscles involved in the control of balance. The purpose of this study was to investigate the balance and lower limb muscle responses to short-duration GVS and to determine whether these responses are modulated by small changes in center of gravity (CoG) and baseline muscle activity occurring during ...
متن کاملHead stabilization by vestibulocollic reflexes during quadrupedal locomotion in monkey.
Little is known about the three-dimensional characteristics of vestibulocollic reflexes during natural locomotion. Here we determined how well head stability is maintained by the angular and linear vestibulocollic reflexes (aVCR, lVCR) during quadrupedal locomotion in rhesus and cynomolgus monkeys. Animals walked on a treadmill at velocities of 0.4-1.25 m/s. Head rotations were represented by E...
متن کاملJaw reflexes evoked by mechanical stimulation of teeth in humans.
Jaw reflexes evoked by mechanical stimulation of teeth in humans. The reflex response of jaw muscles to mechanical stimulation of an upper incisor tooth was investigated using the surface electromyogram (SEMG) of the masseter muscle and the bite force. With a slowly rising stimulus, the reflex response obtained on the masseter SEMG showed three different patterns of reflex responses; sole excit...
متن کاملEffects of galvanic vestibular stimulation on postural limb reflexes
25 26 Quadrupeds maintain the dorsal side up body orientation due to the activity of the 27 postural control system driven by limb mechanoreceptors. Binaural galvanic vestibular 28 stimulation (GVS) causes a lateral body sway towards the anode. Previously we have 29 shown that this new position is actively stabilized, suggesting that GVS changes a set30 point in the reflex mechanisms controllin...
متن کاملMyogenic potentials generated by a click-evoked vestibulocollic reflex.
Electromyograms (EMGs) were recorded from surface electrodes over the sternomastoid muscles and averaged in response to brief (0.1 ms) clicks played through headphones. In normal subjects, clicks 85 to 100 dB above our reference (45 dB SPL: close to perceptual threshold for normal subjects for such clicks) evoked reproducible changes in the averaged EMG beginning at a mean latency of 8.2 ms. Th...
