Descending Influences on Vestibulospinal and Vestibulosympathetic Reflexes
This review considers the integration of vestibular and other signals by the central nervous system pathways that participate in balance control and blood pressure regulation, with an emphasis on how this integration may modify posture-related responses in accordance with behavioral context. Two pathways convey vestibular signals to limb motoneurons: the lateral vestibulospinal tract and reticu...
متن کاملInfluence of static eye and head position on tone-evoked gaze shifts.
The auditory system represents sound-source directions initially in head-centered coordinates. To program eye-head gaze shifts to sounds, the orientation of eyes and head should be incorporated to specify the target relative to the eyes. Here we test (1) whether this transformation involves a stage in which sounds are represented in a world- or a head-centered reference frame, and (2) whether a...

متن کاملInfluence of Static Eye and Head Position on Tone-Evoked Gaze Shifts - Contribution of head to gaze shifts
To program eye-head gaze shifts to sounds, the orientation of eyes and head should be incorporated to specify the target relative to the eyes, and only head orientation should be incorporated to specify the target relative to the head. Here we test whether the eye and head motor systems employ different reference frames for gaze shifts evoked by broadband sounds and pure tones. The head-movemen...
متن کاملHead position influence on stabilographic variables.
PURPOSE Head constitutes 6% of our body weight and significantly influences human body motor system mechanics. From physiological point of view, it should be located at extension of body middle line. Its location being modified results in many consequences in motor system. Our research was aimed at assessing the influence of head position on human body balance stabilographic variables. METHOD...
