g.BSanalyze: EEG-toolbox - gtec's interactive environment for spatio-temporal EEG data processing

Specialized functions for EEG artifact detection  and data quality  computations assure highest-quality results. Adaptive Filtering  or bandpower analyses allow to extract EEG signal parameters. The parameter extraction section includes also the extraction of Hjorth  and Barlow  parameters.

Signal similarities in the time domain are determined by cross-correlation  methods. In the frequency domain coherence  analysis yield linear couplings as function of frequency. Signal Averaging methods allow to determine phase-locked Evoked-Potentials . A section with sophisticated functions for Event-Related Desynchronization  and Event-Related Synchronization analyses allow to investigate stimulus- but non-phase locked EEG phenomena.

The graphical user interface for g.EEGtoolbox  enables you to explore EEG data sets and to extract relevant information that can not be seen from raw data only. Results of multi-channel  computations are visualized in the result2D  tool allowing also topographical arangement  of the results. You can load and save your preferred processing steps as a script program and automatically process your data in batch mode.
