A functional cervical spine disorder is often the cause for persistent vertigo, which can last months or several years. The existence of cervical vertigo is not generally recognized, mainly because an objectivation of the cervical nystagmus is not easily understood by many examiners. In this study we examine additional parameters, which underline the(More)
The steady-state auditory evoked magnetic field and the Pbm, the magnetic counterpart of the second frontocentrally positive middle latency component of the transitory auditory evoked potential, were measured in ten tinnitus patients using a 122-channel gradiometer system. The patients had varying degrees of hearing loss. In all patients, the tinnitus(More)
Two methods for the extension of neuro-modules are introduced resulting in a new behav-ioral functionality. We call them restricted and semi-restricted module expansion. These methods are developed and applied using a modular neuro-dynamics approach to behavior control of autonomous mobile robots. Evolved neuro-controllers which solve an obstacle avoidance(More)
Existing investigations of cervical hearing disorders have been carried out predominantly in patients in whom those with vertebrobasilar insufficiencies (VBI) could not be distinguished from patients suffering from functional deficit of the upper cervical spine. Since two different syndromes exist, no statement can be made about cervical hearing disorders.(More)
In patients with dysphonia, an increased tension of the muscles of the neck as well as of the prelaryngeal muscles is well known to all phoniatrists. Usually the cause of this tension is only seen in pathological phonation or in a psychic base. In the present report it could be demonstrated that this tension causes itself a functional dysphonia. This(More)
To prove the influence of the vertebral nerve on hearing in rabbits, the vertebral artery, together with its sympathetic plexus (n. vertebralis Frank), was unilaterally cut at the height of the first vertebral body, the atlas. Both preoperatively and several times after dissection, auditory and vestibular functions were investigated using BERA and(More)
A chronic irritation in the upper cervical column of 10 rabbits by implantation of a wire string was performed. The vestibular and auditory functions were investigated by electronystagmography and by BERA before and several times after the operation. A distinct increase of the proprioceptive cervical nystagmus was found already in the first postoperative(More)
The limitations of BERA in paedaudiology are demonstrated in the light of some own observations, without depreciating the importance of the BERA. On the one hand there are simple faults in the interpretation, on the other great difficulties exist in the diagnosis of hearing loss above 1000 cps and hypoacusis of a higher degree. In the latter case, BERA(More)
An uncomplicated method to differentiate between an auditory and a vibration threshold. It is a well-known problem that it is very difficult or almost impossible to distinguish in a deaf person between the genuine auditory threshold, especially the bone conduction threshold, and a vibration threshold in the range of low frequencies up to 1000 cps.
