In order to further research cortical impairment in ADHD patients, late auditory evoked potentials were measured. By using paired-chirp auditory late responses, we compared the ADHD group against a control group, focusing on the inhibition elicited by the stimuli. The results show overall smaller amplitudes in the N100 and P200 waves, as well as a reduced inhibition in test chirp for ADHD patients. A frequency study using the wavelet phase synchronization stability transform was made in order to strengthen the results, as well as analysis of variance test for frequency and reproducibility index for amplitude. Both amplitude and frequency show there is an impaired auditory inhibition in ADHD patients, for interstimulus intervals of 500 and 700 ms, and reinforce the knowledge that impairments in this condition are present in multiple cortical areas.

The degree of severity of several psychopathologies coming along with cognitive deficits often impedes the adequate execution of complex cognitive tasks, demanding for objective analysis of cognitive function in an easy-to-follow paradigm for uncooperative patients. The broad availability of electroencephalography (EEG) provides an auspicious base for the development of a fast and reliable tool for the objective diagnosis of pathological cognitive limitations. In the development of the paradigm and follow-up data analysis, we focussed on the objective assessment of the most common cognitive deficits in psychopathological disorders, i.e., limitations in working-memory span and the corresponding loss of attentional resources as well as deficits in facial recognition, contributing to severe social cuts. In a passive face recognition task, we monitored the N170 component of late visual evoked potentials (VEP) in healthy subjects for establishing a methodological base for the diagnostics of cognitive deficits in patients. In line with our preliminary work, we were able to demonstrate a loss of phasic coherence in the single-trial analysis of subsequent visual stimuli during the repetitive face presentation. The novelty event however involuntarily captures attentional resources, resulting in an afresh increase in intertrial phase coherence. These results provide a new viable methodology for accessing the novelty-effect in cognitive deficit patients using a passive visual ERP paradigm of involuntary attentional guidance and habituation.

Listening in noisy situations demands cognitive effort. Recently, we have shown that the Wavelet Phase Synchronization Stability (WPSS) of Auditory Late Responses (ALRs) represents an objective method to estimate mental load in auditory environments. In literature only a limited number of publications can be found which focus on the effects of noise types and noise onset effects using syllable evoked ALRs. The objective of the present work was to analyze the influence of different parameters, like white and babble noise as well as different noise onset times 50, 300, 1000ms and continuous noise conditions, on syllable evoked ALRs. Also, the analysis of the WPSS, as used in previous work, has never been applied to see such effects on the ALRs. We found that noise onset times of 300ms or larger showed a good separation of the ALR components. Furthermore, the analysis of the WPSS for different scales showed a clear identification of the N1 components. However, the best type of noise, and noise onset configuration depends on the specific application. For investigations related to auditory processing of speech, ecological noises are preferred because they could be used to mimic everyday listening situations.

A placebo (sham) stimulation system for transcranial magnetic stimulation was developed and tested. To achieve the placebo stimulation, the existent systems were studied and the goal was to develop an alternative system which considered every non-magnetically induced feature of the real stimulation, masking them by means of electrical and auditory stimulation, as well as a reduced magnetic field output to prevent cortical stimulation. As a result, placebo stimulation offered convincing sensation masking in most of the test subjects, providing an alternative way to perform control experiments.

Nanotechnology is more and more attracting worldwide attention and is deemed to be one of the major future technologies, especially in medical sciences. For medical use, Nanoparticles (NPs) offer a wide spectrum of applications since they seem to be able to move through organic tissue without barriers. This can be beneficial on the one hand and can bear risks on the other. Nanotoxicity research has already set in, but there are still many open questions that have to be addressed. Based on our previous study of investigating some electrophysi-ological effects of NPs on neuronal cells, in this article we now integrate our results to possible effects of NPs on network dynamics: a theoretical model of thalamocortical interactions is used to detect changes in resonance processes due to NPs ”in silico”. The mathematical model is based on the Llinas model of cortico-subcortical neurodynamics. For this particular purpose, each single neuron model within a simplified thalamocortical circuit is described by an extended Hodgkin-Huxley type formalism (in which all ionic currents are considered to reproduce the main firing patterns observable in these neurons). We found differences of NP induced firing patterns in cortical pyramidal cells and interneurons by simulating NP interference in thalamic cells. Our simulation results suggest that NP in neuronal feedback circuits influence synchronization processes across multiple cortical areas and thus hindering the integration of multimodal information into a single cognitive event.

Large-scale neural correlates of auditory selective attention reflected in the electroencephalogram (EEG) have been identified by using the complex wavelet-phase stability measure (WPS). In this paper, we study the feasibility of using the WPS in extracting the correlates of selective attention by comparing its performance to the widely used linear interdependency measures, i.e., the wavelet coherence and the correlation coefficient. The outcome reveals that the phase measure outperforms the others in discriminating the attended and unattended single sweep auditory late responses (ALRs). Particularly, the number of response sweeps that are needed to perform the differentiation is largely reduced by using the proposed measure. It is concluded that a faster (in terms of using fewer sweeps) and more robust objective quantification of selective attention can be achieved by using the phase stability measure.

The basic approaches to fit hearing aids were commonly based on findings of how young persons hear sounds in ideal conditions. In order to improve hearing aid fitting methods, the focus of the new approaches should be based on auditory processing and cognition information of older adults. In previous studies with young subjects, employing tonebursts and in noise embedded syllabic paradigms, we have shown that the Wavelet Phase Synchronization Stability (WPSS) of Auditory Late Responses (ALRs) can serve as an objective indicator of listening effort. The purpose of this preliminary work, which precedes a study with hearing impaired persons, is to examine possible age-related differences in the WPSS and ALRs by testing syllabic paradigms in two different age groups and using two different levels of task complexity. The WPSS discriminated between difficult and easy test conditions, which is in line with our previous findings. The latest was consistent in both age groups. Age-related differences regarding the WPSS could not be observed.

Objective methods to asses listening effort are still missing in clinical settings. Thus, the focus of our ongoing research is the extraction of possible substrates of listening effort. This paper focuses on the non-effort related factor reaction time (RT) on the different components of auditory late responses (ALRs). It makes sense to consider this factor in the context of age related changes of the RT. For the comparison of the ALR components and the RT, two syllable oddball paradigms with different degree of difficulty were created. The paradigms were embedded in multitalker babble noise to create a realistic listening situation. The data was collected from 13 normal hearing healthy subjects, who had to detect a deviant. Furthermore, the wavelet phase synchronization stability (WPSS) was calculated for different scales. A filter bank was designed in order to separate the components by their frequency content. Finally, the Pearson product-moment correlation coefficient was calculated to clarify if there is a possible linkage between the RT and the ALR components. The results show, that only the P 3 latency is correlated with the RT. A relation between the RT and the other ALR components could not be observed. It is concluded, that the focus of our further research, will be on the N 1 and the P 2 wave due to the fact that those components are independent from the non- effort related factor reaction time.

Until now, an objective method to estimate listening effort with a minimum level of cooperation of the patient in order to fit hearing aids is not existent. The benefit of such a method would be to reduce the listening effort in hearing impaired persons by an adequate adaption of the hearing aids. Recently, we have shown that the wavelet phase synchronization stability (WPSS) of auditory late responses could serve as a measure to estimate listening effort. In this paper, we extend our previous studies by using for the first time syllable stimulation paradigms with two levels of difficulty due to the combination of the syllables. Furthermore, by taking the model of auditory stream selection into account, the complexity of the paradigms was enhanced by the generation of a second competing auditory stream beside the syllable stream. This stream consisted of multitalker babble noise at two different signal to noise ratios in order to mimic noisy environments. The data was collected from a total of 21 normal hearing subjects, who had always to detect a target syllable. It is concluded, that the WPSS is a robust measure to perceive differences between the effort needed to solve a task in an easy and a difficult listening condition. However, a further research will be to test hearing impaired persons to prove, if this electrophysiological method could be applied to improve the hearing aid fitting procedures in clinical settings.
