Sonifications for eeg data analysis
TLDR
Three sonifications are presented within this paper: spectral mapping sonification, which offers a quite direct inspection of the recorded data, distance matrix sonification which allows to detect nonlinear long range correlations at high time resolution, and differential sonificationWhich summarizes the comparison of EEG measurements under different conditions for each subject.Abstract:
This paper presents techniques to render acoustic representations for EEG data. In our case, data are obtained from psycholinguistic experiments where subjects are exposed to three different conditions based on different auditory stimuli. The goal of this research is to uncover elements of neural processing correlated with high-level cognitive activity. Three sonifications are presented within this paper: spectral mapping sonification which offers a quite direct inspection of the recorded data, distance matrix sonification which allows to detect nonlinear long range correlations at high time resolution, and differential sonification which summarizes the comparison of EEG measurements under different conditions for each subject. This paper describes the techniques and presents sonification examples for experimental data.read more

TL;DR: Results confirm two hypotheses formulated in a preliminary study: pitch is by far the most used auditory dimension in sonification applications, and spatial auditory dimensions are almost exclusively used to sonify kinematic quantities.

Parametric orchestral sonification of EEG in real time
Thilo Hinterberger,Gerold Baier +1 more
TL;DR: Subjects' ability to perform a discrimination task with parametric sonification in real time is studied.
Supplementary Material for "Event-based sonification of EEG rhythms in real time"
TL;DR: In this article, an event-based sonification was proposed to detect and identify different types of EEE events in real time and can be used to complement visual displays in monitoring and EEG feedback tasks.

Event-based sonification of EEG rhythms in real time
TL;DR: The proposed event-based sonification allows quick detection and identification of different types of rhythmic EEE events in real time and can thus be used to complement visual displays in monitoring and EEG feedback tasks.

Sonification and textification: Proposing methods for classifying unspoken words from EEG signals
Erick Fernando González-Castañeda,Alejandro A. Torres-García,Carlos A. Reyes-García,Luis Villaseñor-Pineda +3 more
TL;DR: Whether these techniques can help to do a better discrimination or to highlight patterns, and which of the two methods performs better in order to improve classification results of unspoken words is analyzed.

TL;DR: The main thrust of Electroencephalography is to preserve the sound basis of classic EEG recording and reading and, on the other hand, to present the newest developments for future EEG/neurophysiology research, especially in view of the highest brain functions as mentioned in this paper.

TL;DR: Results indicate that the alpha 1-band reflects cognitive processes that were common to both word classes, whereas the beta 1- band seems to be closely related to associative processes and more complex cognitive functions.
