difference ( Nd ) event - related potential
Frontal and temporal lobe sources for electrical activity associated with auditory controlled attention (negative difference, Nd) were sought for comparison with those reported to arise from the earlier detection of stimulus-change (mismatch negativity, MMN: Jemel et al. 2002). In two sessions a month apart (T1 and T2), 14 subjects were presented with a 3-tone oddball passively, then as a discr...
متن کاملHz Event Related Auditory Potential
Main focus of this paper is an EEG experiment on observing frequency of event related auditory potential in response to series of clicks. Based on the past research, it was expected to observe 40 Hz potential, which was not the case. The experiment was conducted on one subject, and the average observed frequency of 61 Hz could be explained by individual differences. However, an additional step ...
متن کاملSingle-Trial Event-Related Potential Analysis for Brain- Computer Interfaces
Different types of mental activity are utilised as an input in Brain-Computer Interface (BCI) systems. One such activity type is based on Event-Related Potentials (ERPs). The characteristics of ERPs are not visible in single-trials, thus averaging over a number of trials is necessary before the signals become usable. An improvement in ERP-based BCI operation and system usability could be obtain...
متن کاملEvaluation of Empirical Mode Decomposition for Event-Related Potential Analysis
Current methods for estimating event-related potentials (ERPs) assume stationarity of the signal. Empirical Mode Decomposition (EMD) is a data-driven decomposition technique that does not assume stationarity. We evaluated an EMD-based method for estimating the ERP. On simulated data, EMD substantially reduced background EEG while retaining the ERP. EMD-denoised single trials also estimated shap...
متن کاملINDEPENDENT COMPONENT ANALYSIS OF ELECTROENCEPHALOGRAPHIC AhJD EVENT-RELATED POTENTIAL DATA
The electroencephalogram (EEG) is a non-invasive measure of brain electrical activity recorded as changes in potential difference between points on the human scalp. Because of volume conduction through cerebrospinal fluid, skull and scalp, EEG data collected from any point on the scalp includes activity from processes occurring within a large brain volume. Event-related potentials (ERP) are the...
