متن کاملDescending 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 کاملVisuoocular reflexes in presbyvertigo.
Using electronystagmography, we tested 100 patients (ages 65-80 years) manifesting the clinical signs of presbyvertigo, for the purpose of demonstrating their visuoocular reflexes. We administered not only simple optokinetic and eye-tracking stimuli but caloric modification of each one as well (with contrary directed optokinetic trace movement). The results were compared with those obtained in ...
