Several data indicate that compensation and habituation processes are the main phenomenons of the plasticity of central nervous system (CNS), especially the plasticity of vestibular system. The detailed role of particular parts of CNS in adapatation after lessions has not been clear yet (2). Evertbody knows that in birds and reptiles cerebral motor cortex in […]
The vertebral artery origins from the subclavian artery, moves cranially and penetrates into the “foramen magnum” to meet the cotralateral artery so to origin the basilary artery. The length of the vertebral artery is approx. 25 cm. with a diameter between 3 and 6 mm. In 60% of the normal population, the vertebral arteries don’t […]
It seems to be very interesting to compare the results of the vestibular testing and the somatosensory evoked potentials (SEP) in cases with cervical diseases. This multimodal neurophysiological analysis of the patients suffering from cervical spondylosis before and after neurosurgical treatment is the first part of this long-term study.
The objective of this study is the supposition, verified through suitable hematochemical tests, of the co-presence in the etiopathogenesis of the Menière syndrome and/or in the labyrinth pathologies or hypacusia also of central/systemic microtoxicosis. We do not therefore exclude other well known hypotheses on the causality of these pathologies, but one finds, above all in […]
The possible relationship between inner ear and vasopressin (AVP, ADH) has been hypothesized since twenty years ago About ten years ago, in anaesthetized guinea pigs, we demonstrated that changes in the inner ear pressure modify plasma AVP (pAVP) level and AVP secretion with consequent changes in urine flow rate and osmolality : our experiment was […]
Whiplash injuries induce abnormalities in head-trunk control due both direct impact on the neck and indirect involvement of the central vestibular system. It is usually difficult to document specific abnormalities due to whiplash injuries. We stated that examinations aimed to document head-trunk coordination involvement could be useful in the functional assessment of vestibular disorders in […]
The variety of suggested treatments of nystagmus probably reflect its multiple pathogenetic mechanisms. Basic studies have shown that several neurotransmitters are involved in the ocular motor control, including gamma-aminobutyrric acid (GABA), acetylcholine and glycine. Recently, Stahl et al. (1995 ) investigated the effects of gabapentine on acquired pendular nystagmus in two patients with multiple sclerosis. […]
Según nuestra experiencia el sistema vascular y su influencia bajo estímulos simpáticos y parasimpáticos juega un rol fundamental en la neurofisiología del equilibrio. Toda modificación del calibre arterial ya sea a nivel periférico o central bajo la dependencia del sistema simpático puede originar trastornos de nutrición a nivel de las células con modificación de sus […]
Bei dem sogenannten Halsschleudertrauma handelt es sich um eine neuartige Zivilisationskrankheit, die wir vor allem in der Häufung, in der wir sie heute antreffen, zu Beginn dieses Jahrhunderts noch nicht gekannt haben.
