Homage to prof. dr. bernhard hofferberth
It is a great privilege for me and my wife Julia, having been appointed to honour Prof. Dr. Bernhard Hofferberth, to whom we are friendly bound since 25 years ago, both in the scientific and personal field.

Doppler ultrasonography in tinnitus patients
Tinnitus can be functionally measured and localized through sensorimotor and neurosensory tests. According to our Neurofisiología Otooftalmológica data bank, 60% of patients requiring a consultation have a history of cardiocirculatory disorders. This figure has moved us to study cerebrovascular processes in those patients seeking consultation for a tinnitus symptom only. The sudden appearance of the […]
Response of human skull to bone-conducted sound in the audiometric-ultrasonic range
Some new therapies for tinnitus employ bone-conducted sound in the high audio and ultrasonic frequencies, but there has been little previous research on sound transmission through the head at these frequencies.
Vertigo as a prognostic sign in sudden sensorineural hearing loss
Several prognostic indicators of favorable outcome in idiopathic sudden sensorineural hearing loss (ISSHL) have been proposed: an initial profound hearing loss, a down-sloping audiometric curve, advanced age, and the presence of vertigo. The latter has been disputed in the literature. The present study addressed the correlation between vertigo and outcome of ISSHL. Sixty-seven patients with […]
Vertigo and migraine
The vascular system and its influence under sympathetic and parasympathetic stimulations plays an essential role in neurophysiology of equilibrium.
Bppv and vasopressine
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 […]
Vestibular evoked potentials (vbep): methodological and systematical aspects
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».
Navigation test
The balance system allows to our body to have a right relation with environment, this is probably due by different structures that collaborate to maintain the correct voluntary posture during erect position and the clear vision of the ambience; with regard to its synergetic purpose the balance system can therefore be schematised on the base […]
The role of subcortical motor neurons in balance disorders- experimental study of the plasticity of the system
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 […]
La riabilitazione dell’adolescente sordo preverbale
L’Impianto cocleare che ha nei sordi postverbali e nei bambini impiantati precocemente i suoi candidati ideali, deve oggi confrontarsi con un’altra categoria di pazienti, sicuramente più difficili, come gli adolescenti sordi preverbali. Per questi ultimi, la terapia riabilitativa e le performances che si possono ottenere hanno una vasta variabilità sia sotto l’aspetto quantitativo che qualitativo […]
