The vestibular pathway, like other sensorial systems, has a cortical representation. In 1985 we have published our first investigation on «Variations of the cortical electrical activity during supramaximal vestibular stimulations».
THE ROLE OF THE VESTIBULAR SYSTEM IS TO INTEGRATE POLISENSORIAL CUES AND PROVIDE A CONTINUOS AND PRECISE REPRESENTATION EITHER OF THE BODY SHAPE (SEGMENTAL BODY ORIENTATION, THAT TO SAY PERCEPTION OF THE RECIPROCAL POSITION OF BODY SEGMENTS ) OR THE ORIENTATION OF THE BODY INTO THE ENVIRONMENT (SPATIAL ORIENTATION). MELATONIN IS A NATURAL HORMONE SECRETED […]
The cranial shifting of body fluids developing in microgravity can be modelled by –300 head-down tilt body position (antiorthostatic posture) on Earth. Authors examined a group of 13 healthy voluntary young men in antiorthostatic posture and recorded the alteration of parameters in complex examinations. Among them pure tone threshold and speech threshold examinations were carried […]
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 […]
TETRAATAXIOMETRY (BY TETRAX, ISRAEL) IS A THE LAST VERSION OF STATIC POSTUROGRAPHY ALLOWING SIMULTANEOUS RECORDING OF FORCES APPLIED AT RIGHT AND LEFT FOOT AND RIGHT AND LEFT TOES AND HEELS. IN THIS WAY IT IS POSSIBLE TO ASSESS BOTH GLOBAL BALANCE AND THE SPECIFIC COORDINATION OF RIGHT, LEFT, ANTERIOR AND POSTERIOR PARTS OF THE BODY […]
It has been demonstrated not only in our experimental research as well as in our clinical routine that the association of different strategies is usually highly synergic for positional vertigo relief and control. The summation of the various favourable effects of each kind of therapy seems to lead to an improvement or cure which is […]
The usefulness of conventional posturography when the changes of muscle tonus of the lower limbs affect position of the center of gravity which movement is measured is well known. The radius of the gravity center deflection such as length of the „way” and velocity of the movement can be calculated and compared during sequences with […]
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 […]
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 […]
