The activity of 68 neurons, mainly Purkinje cells, was recorded from the cerebellar anterior vermis of decerebrate cats during wobble of the whole animal (at 0.156 Hz, 5 degrees), a mixture of tilt and rotation, leading to stimulation of labyrinth receptors. Most of the neurons (65/68) were affected by both clockwise and counterclockwise rotations.(More)
Vertigo and postural instability following whiplash and/or minor head injuries is very frequent. According to some authors, post-whiplash vertigo cannot be caused by real injury to vestibular structures; other authors maintain that vestibular damage is possible even in the case of isolated whiplash, with vascular or post-traumatic involvement. Furthermore,(More)
Previous studies on the role of hypnotizability in postural control indicate that the body sway of subjects with high or low hypnotizability to hypnosis is differentially modulated by eye closure. The aim of this study was to investigate whether hypnotizability also modulates the postural response to electrical vestibular stimulation and to head rotation in(More)
Changing the foot position modifies the mechanical action exerted by the ankle extensor and flexor muscles over the body. We verified, in two groups of healthy subjects standing with the heels touching or apart, whether a 90° external rotation of the right leg and foot also changes the pattern of vestibulospinal reflexes elicited by electrical stimulation(More)
The responses of the forelimb extensor triceps brachii (TB) to sinusoidal wrist rotation, at 0.156 Hz, +/-5 degrees, were investigated in decerebrate cats. In most of the tested muscles [12/15) the multiunit electromyographic (EMG) activity of the TB muscle increased during dorsiflexion and decreased during plantar flexion of the ipsilateral limb extremity,(More)
Betahistine, a drug used in the treatment of vestibular disorders, speeds-up the recovery from hemilabyrinthectomy in experimental animals, likely through the activation of histamine receptors. In order to better understand the mechanism of action of this drug we investigated, in adult, urethane anesthetized rats, whether betahistine modifies the spatial(More)
Middle ear implants overcome some of the common problems of conventional hearing aid technology, such as feedback, signal distortion, ear canal occlusion and associated issues. The Otologics MET Carina, Boulder, CO, USA, is a fully implantable hearing prosthesis designed to address the amplification needs of adults (> 18 years of age), with moderate to(More)
OBJECTIVE An alternative transcanal surgical technique named "exclusive transcanal approach" for Vibrant Soundbridge (VSB) implantation is presented. The surgical steps and our experience in a series of 12 patients are reported. STUDY DESIGN Retrospective study. SETTING : Tertiary referral center. University hospital. PATIENTS Twelve patients, 8 women(More)
The aim of this systematic review was to summarize the results of scientific publications on the clinical effectiveness of the cochlear implant (CI) procedure in adults. The members of the Working Group first examined existing research evidence from the national and international literature and main international guidelines. They considered as universally(More)
In decerebrate cats, sinusoidal rotation of the forepaw around the wrist modifies the activity of the ipsilateral forelimb extensor triceps brachii (TB) and leads to plastic changes of adaptive nature in the gain of vestibulospinal (VS) reflexes (VSRs). Both effects are depressed by functional inactivation of the cerebellar anterior vermis, which also(More)
