How to cite this article Schneider D, Schneider L, Shulman A, Claussen C, Just E, Koitchev C, Kersebaum M, et al. Tinnitus is one of the most important symptoms in neurootology after vertigo, nausea, and hearing loss. In the course of the last few years, we have used the technology of brain mapping of electrical activity as measured during angular vestibular accelerations in the neurootology department at the University Head Center of Wurzburg. An anatomical plan in sagittal and coronal cerebral sections measured from the vertex toward the foramen magnum with a display of important neuroanatomical structures, controlled by the central nervous system (CNS), which regulates both hearing and equilibrium control, thus demonstrates how closely spatioacoustic processors are interrelated. The flrst two functions share common pathways with other neurosensory functions and encompass the sense of interaction within the sensorineural framework.
Our studies encompassed two different therapeutic modalities In one study involving five patients (four women, one man), drug therapy for tinnitus was attempted using a standardized extract of Gingko biloba (EGB 761) [3]. In the other study, a special competitive kinesthetic therapy was employed to attempt tinnitus control in 20 patients. The VestEP pattern represents a wave complex of six negative-positive deflections within the interval of 65-800 msec after onset of the vestibular acceleration step. Whole vestibular potential toward negativity when rotating to the direction of the affected side is of particular interest. A 63-year-old female patient had suffered from left tinnitus of the severe, disabling type for 3 years. After 8 weeks of Ginkgo biloba therapy, a clear subjective improvement was seen in her condition in terms of reduced volume of tinnitus and generally improved perception of quality of life. A 49-year-old female patient had suffered from left tinnitus of the severe, disabling type for 9 years.
After 8 weeks of Ginkgo biloba therapy, the patient exhibited a clear subjective improvement of the tinnitus condition. A 62-year-old male patient had suffered from bilateral tinnitus of the severe, disabling type for 8 years.
After 4 weeks of competitive kinesthetic therapy, clear subjective improvement of the tinnitus was noted in terms of reduced volume and generally improved perception of quality of life. Fundamentally, the character of the electro graphical VestEP changes in the group of tinnitus patients is that of irritation. Perfusion asymmetries in tinnitus patients are demonstrated in other work by Shulman et al.
Connections between the limbic and acoustic systems have been subject to discussion for a long time. EGB 761 influenced excitatory states of the vestibuloacoustic system and is effective in the treatment of central excitatory tinnitus.
A man in his 20's presented to the clinic with a 1 month history of dizziness, imbalance, and a hearing disturbance. On examination (at about 1 month post onset), there was a low amplitude left-beating spontaneous nystagmus. The one week delay in onset of hearing symptoms suggests that there was progression of the disease process in this case over a week.
Gingko biloba (Rokan) Therapy in Tinnitus Patients and Measurable Interactions Between Tinnitus and Vestibular Disturbances. With this modality, we have successfully measured (and analyzed, using computerassisted drafting techniques) late vestibular evoked potentials (VestEP), obtained from electrodes located on the scalp during repeated accelerations of the affected patient. Further, telencephalic and diencephalic supervisory loops modulate the activity in this area.
Preliminary results of the therapy using extract of Ginkgo biloba (EGB 761) seem to be very promising in tinnitus therapy.
The biosignals are transmitted to the main amplifier through a slip-ring assembly containing 17 slip rings, each fitted with twin sliding contacts. Even so, individual hearing protectors (Bilsom Propp-oPlast, Sweden) are applied to both ears of the patient to avoid any possible acoustic contribution to the rotationally evoked potentials. In this study, an analysis was performed on the basis of the main latency-amplitude properties of the VestEP, obtained from the C3 (left central) and C4 (right central) electrode derivations. On brain-mapping displ ay, this appears as an intense red map, when mapping, for example, the third VestEP component.
Additionally, however, objective measurements clearly indicated a normalization of the VestEP findings.

Rotation to the left produced an intense prolongation of the earlier finding of shortened latencies and an adjustment of the latencies during clockwise and counterclockwise rotation (Figs.

Animal trials provided evidence that glutaminergic pathways play an important role in this context. These first results of tinnitus therapy by means of EGB 761 in 5 patients and of compehtlve kinesthetic therapy is 20 patients are very promising. Speckmann E-J, Elger CEo Introduction to the Neurophysiological Basis of the EEG and DC Potentials. The unusual aspects are the cochlear enhancement on the MRI, and the one-week delay in onset of hearing symptoms. This is not usual in either labyrinthitis or vestibular neuritis, but might occur due to spread of the infection, or other pathologic mechanisms such as poor circulation to the inner ear.
The scalp-referred brain electrical activity mapping (BEAM) images indicate characteristic changes in patients with tinnitus [1]. As currently understood, the read-only memory functions of the basal ganglia play an important role in establishing driving patterns for various neurosensory internal and external transitions. The amplification and paper monitoring of the raw electroencephalographic (EEG) data are accomplished using a 17-channel Picker Schwarzer Encephaloscript ES 16000. The patients, all of whom suffered from tinnitus of the severe, disabling type, were treated by a daily infusion of 200 mg EGB 761 for 7 days and afterward with an oral application of 160 mg EGB 761 (two single doses daily) for an additional 7 days. The treatment involves analysis and, if necessary, correction of whole-body expressions and global movement programs of the patient. Rotation to the right and to the left demonstrated an intense prolongation of the earlier finding of shortened latencies and an adjustment of the latencies during clockwise and counterclockwise rotation (see Table 1). The perceived auditory quality of the tinnitus was a loud murmur, and a side localization no longer was possible.
Rotation to the right and to the left demonstrated an intense prolongation of the earlier finding of shortened latencies (see Table 3) and a disappearance of the negative DC shift (Fig. Consequently, potential differences between the referential point (which is practically electrically silent) and each one of the scalp electrodes (which is electronegative with respect to the reference point) reflect the gradient of the relative cortical electronegativity during vestibular stimulation. If inhibitory gammaaminobutyric acid-related interneurons are blocked, which normally inhibit the effect of the excitatory glutaminergic system, seizures are induced [13].
It is postulated that these methods will open a new direction in the treatment of tinnitus.
On the functional state of central vestibular structures in monaural symptomatic tinnitus patients.
Randomisierte placebokontrollierte doppelblinde Multicenterstudie zur Wirksamkeit von Rokan bei Tinnitus. Vestibular evoked potentials (VestEP) and brain electrical activity mapping-a test of vestibular function-a review (1990-1996). In E Niedermeyer, F Lopes da Silva (eds), Electroencephalography: Basic Principles, Clinical Applications and Related Fields. The functional neuroanatomy of tinnitus: Evidence for limbic system links and neural plasticity. One week later, hearing deteriorated on the right side, accompanied by tinnitus, a headache and ear pain.
While there is a general agreement that MRI is useful to exclude the presence of tumors in persons with unilateral hearing loss, a careful consideration of the cost-benefit ratio in persons with sudden hearing loss (such as is the case in labyrinthitis), to our knowledge, has not been done. Therefore, a modern concept of tinnitology must consider that afferent hearing is composed primarily of three discreteand equally important-information chains, which are linked to acoustic space control, acoustic modulations of individual and social emotions, and acoustic transfer of intellectual (i.e.
The stimulus profile, programmed by a specially constructed function generator, takes the form of a raised-declined cosine impulse with a duration of 1.0 seconds in each phase. To minimize eye movement- related artifacts, gaze fixation is controlled through a structured fixation target that rotates with the chair. The derivation type that is adopted is monopolar, with a common reference electrode fixed over both mastoid bones.

Just observed in some patients during therapy for orthopedic disturbances an alteration in the finding of tinnitus.
Because of the relatively low number of treated subjects, we did not attempt a statistical survey but instead present two typical cases from the Gingko biloba group and one typical case from the competitive kinesthetic therapy group. The perceived auditory quality of the tinnitus was a loud murmur, and the noise could not be masked. The quality of the tinnitus was a constant noise of severe intensity, and it could not be masked. OAE's may be present when the hearing loss is being simulated or exaggerated, or when there is an auditory neuropathy causing the hearing loss. In our practice in Chicago Illinois, we commonly do obtain a 3T MRI with contrast in any person with an unexplained substantial, sensorineural hearing loss.
The chair is housed in a partially lighted room, which permits the examination to be carried out either in total darkness or in an illuminated environment. Upward deflections indicate scalp negativity, and downward deflections indicate positivity. Intrigued by this preliminary finding, the team at our neurootological department conducted electrophysiological investigations of this phenomenon [5], after which Just and Dehler further developed competitive kinesthetic therapy. At present, according to former studies of our working group [1,5,6], three primary main findings are determined in patients with tinnitus: (1) shortening of the latencies from the first to the fourth VestEP components, (2) increased amplitude of the III-IV peak-to-peak component, and (3) DC shift of all VestEP components toward the negative pole. If an afferent influx of impulses occurs in vertically oriented cortical neurons at a high frequency for a longer period, wavelike excitatory postsynaptic potentials will be generated at the superficial dendritic arborization. We prefer the higher resolution study (3T) compared to the lower and more usual resolution of 1.5 T, as the cochlea is a very small structure and small changes can be hard to see even on a very good MRI scan. From this starting point, a great demand exists today for new ideas and developments in the diagnosis and treatment of tinnitus. This montage and derivation configuration is chosen after numerous tests to determine orientation.
These VestEP-modifications are particularly clear in cases of monolateral tinnitus, in which the comparison is made between the VestEP parameters obtained when the rotation is directed to the side of the affected (tinnitus) ear versus rotation toward the side of the non affected ear.
Using this method of gaze fixation clearly shows that a wellmarked suppression of the rotatory evoked nystagmus has taken place. The frequency band of the recorded spontaneous brain electrical activity is determined by a low-frequency cutoff at 0.1 Hz and a high-frequency cutoff at 35 Hz. Shortening of latency IV can be seen during rotation to the left (in relation to the rotation to the right).
Shortening of the latencies (especially the late waves) can be seen during rotation to the right.
This prolonged depolarization of the superficial structures caused by sensory afferentation manifests itself by a negative shift in the EEG, in particular the negative DC-EEG potential shift [7]. A bilateral destruction of the hippocampus leads to a loss of the ability to learn new things. In addition, the clinician should recognize a slight CD shift of the curve toward negativity. In addition, affected patients are not able to remember things they had learned a short time before the destruction of the hippocampus.
In left rotation, shortening of the latencies is less clear, but a clear shift of the curve toward negativity is found, especially in the late waves (Fig. An interval of 1,000 msec after onset of the stepwise acceleration stimulus is used for analysis of the rotationally evoked brain electrical events.
Shulman [9] postulated a "final common pathway for tinnitus" in all patients with tinnitus of the severe, disabling type in the medial temporal lobe system. Peak-to-peak amplitudes and principal component latencies are measured and subsequently are computed on a personal computer (Macintosh, Cupertino, CA) for their averaged values and standard deviations. Perfusion asymmetries in the hippocampus-amygdala complex were demonstrated by single-photon emission computed tomography (SPECT). He stated the presence of a "paradoxical memory" for an aberrant auditory signal within these brain structures.
