Vestibular and optokinetic nystagmus in the ketamine-anesthetized rabbit.
Ketamine, or ketamine hydrochloride, is a non-barbiturate, rapid-acting disassociative anesthetic: the primary central nervous system action of ketamine appears to be a non-competitive block of NMDA (named after the selective agonist N-methyl-D-aspartate). In the current study, we examined the effect of ketamine on cortical and subcortical function by exploiting evoked eye movements: we analyzed the […]
La stabilizzazione dinamica della testa sul tronco durante il cammino
Head stabilization is necessary during human locomotion in order to contrubute to perception of a stable visual field. Head stabilization is du to the cooperation between vestibular system and proprioception. According to cranio-corpographic experience Authors used a device based on two accelormeters place, respectevely, on th head and the trunk of the subject. Head stabilization […]
The diagnostic value of isolated preponderance in caloric testing
Objectives: An isolated directional preponderance (PD) on bithermal caloric testing leaves many doubts to neurootology. It is considered by some to be as a transient, benign disorder (Halmagy, GM et al). We tried to elucidate if the PD can be considered important for the clinical diagnosis, without anamnesis. Methods: A retrospective study of 136 electronystagmographies, […]
P-100 in the treatment of Ménière’s disease, a clinical study
Patients suffering from Ménière’s disease are particularly sensitive to negative pressure in the middle ear. E.g. attacks of vertigo can be triggered by a descent in an aircraft when ventilation of the middle ear can become critical. Positive pressure pulse treatment has shown to have a beneficial effect on the symptomatology, and is now a […]
Comparative results of the craniocorpography (ccg) and test of balance
Many authors had reported different useful studies in the evaluation of the vestibular function through vestibular, somatosensorial, viso-cortical systems in the Test of Balance.1,8 and to study the vestibular function through vestibuloespinal system in the Cranio-Corpo-Graphy (CCG) 2,3,4 Upon researching 100 patients suffering from vertigo we found that 36 % of them were male patients […]
Unexpected effects of air pollution on inner ear
Paroxysmal Positional Vertigo (PPV) is the most frequent kind of vertigo. It is a recognized as an inner ear problem caused by small calcium carbonate crystals that float through the inner ear fluid and strike against the cupula of semicircular canal. Authors have observed in a retrospective statistical analysis of 575 patients through 5 years […]
3d digital craniocorpography: normalcy data
CranioCorpoGraphy (CCG) is one of the most common test to evaluate equilibrium and coordination, studying the pattern of movement of markers placed on the head and trunk. The aim of this work is the assess the coordination of healthy people in different experimental set-ups through a 3D dCCG system. So an optoelectronic system in a […]
Studying the perceptions of movement and movement speed of objects in adolescent drivers
This work aims to study in adolescent drivers whose vestibulo-visual-auditory functions are exposed to the systematic effect of specific mechanical irritants (accelerations, velocities, noise, vibrations, optokinetic effects, etc.), the particularities of the functioning of the higher specialized sensuousness and in particular the vestibular effect on the visual system at formation of the perceptions of movement […]
