The Uhl’s disease, known also as arrythmogenic right ventricular cardiomyopathy (ARVC) may be a cause of sudden cardiac death in young people [3]. Application ofthe Standard linear and new nonlinear methods to investigation of macroscopic physical aspects of this pathology, especially those which provide information for risk analysis, and predict the development of this disease in its early stage, seems to be a very promising task for the biomagnetic studies especially when combined with multich...

Endogenous auditory sensations occur without simultaneous reception of an external acoustic stimulus. They can occur under physiological conditions, but can also be associated with pathological processes. A commonly known sensation of the second kind is tinnitus, or ringing in the ear, a frequent symptom which is often associated with several hearing disorders. A sensation of the first kind is the auditory afterimage. Contrary to the vision system in which after-images have been known for a long...

Effects of anesthetics on electroencephalographic (EEG) activity are used to localize brain lesions as well as epileptogenic areas. Small doses of barbiturates (up to 200 mg) result in an increase of fast activity in the β-band of the EEG. This increase of β-band activity is known to be larger over normal brain areas as compared to areas with cerebral lesions (e.g. [1]). Furthermore, it has been reported that some barbiturates as amobarbital, thiopental, or methohexital or other narcotics as pro...

Research during the last decade has shown that specific aspects of brain dynamics can be determined by using tools from nonlinear system’s theory [1]. Based on a suggestion of Kaplan and Glass [2] it is possible to obtain information about the determinism of a time series even for short measurement intervals. The present study compares the determinism of the MEG in tinnitus patients with that of controls. Given that the auditory cortex is the final link in a chain producing tinnitus, then differ...

A method for the objective evaluation of the hearing threshold using cortical evoked response audiometry was developed. The method results in a kind of objective audiogram, visualizing the significanc

THE auditory afterimage is a sensation which occurs for several seconds after the exciting acoustic signal has been switched off, and which roughly corresponds to the inverse of the spectrum of the exciting signal. In contrast to the well-known visual afterimage, the physiological mechanism generating the auditory afterimage has been questionable so far. Neuromagnetic source imaging revealed that the source of cortical neural activity which coincides with the sensation of the afterimage is locat...

Acoustic stimuli are processed throughout the auditory projection pathway, including the neocortex, by neurons that are aggregated into ‘tonotopic’ maps according to their specific frequency tunings1,2,3. Research on animals has shown that tonotopic representations are not statically fixed in the adult organism but can reorganize after damage to the cochlea4 or after training the intact subject to discriminate between auditory stimuli5. Here we used functional magnetic source imaging (single dip...

The deterministic character of cortical processes in the human brain invites an assessment of nonlinear methods of analysis and exploration of their applicability. Because brain processes are frequently nonstationary, questions arise as to the validity of formal assumptions. Here we present a simple algorithm for estimation of the local divergence measure (Mayer-Kress 1994, Kowalik and Elbert 1994) based on the local Lyapunov exponent (Wolff, 1992) that can be used for nonstationary data.1
