EEGFocus 3.0 Focus EEG ERPs DSA Voltage current source density CSD Laplacian FFT spectral amplitude power 3D spectral analysis
EEGFocus combina análise de EEG digital com recursos de análise avançadas, tais como mapeamento 3D cabeça inteira, de origem cerebral e montagens de imagens, pesquisa padrão espiga e médias, análise espectral, análise de tendência DSA, correção on-line do olho e artefatos de EKG etc Review EEG Digital EEGFocus fornece uma interface amigável para análise imediata de padrões anormais durante a revisão, por exemplo, picos ou EEG atividades rítmicas. Padrões semelhantes podem ser pesquisados no total e média de EEG, por exemplo, para analisar um aumento ou aparecimento de crises. botões ergonômicos e funções-chave para paginação rápido manual ou automático. paginação Overlapped para detectar anormalidades EEG nos limites da página. ferramenta fácil de medir picos e de frequências Vídeo sincronizado paginação, opcionalmente, com o mapeamento cabeça inteira Navegação rápida através da barra do evento ou a mostrar tendência DSA com a separação dos hemisférios (DSA = densidade espectral de matrizes) filtros digitais avançadas, incluindo mudança de fase zero, banda e notch filtros EEGFocus 3.0 EEG analysis 3D spectral analysis, DSA trend analysis, on-line correction of eye and EKG artifacts Digital EEG Review Spikes or rhythmic EEG activities. To analyze a spike or seizure onset. Video synchronized Fast navigation using the event bar or the DSA trend display with separation of the hemispheres (DSA = density spectral arrays) Advanced digital filters including zero-phase shift, band and notch filters For an introduction to advanced digital EEG review and brain source montages we recommend the following lectures: Available map types are: Voltage, current source density (CSD / Laplacian), FFT spectral amplitude, power, or phase Voltage or CSD signals based on spherical spline interpolation Brain source montages available for frontal, temporal, central and parietal brain regions, as well as for standard AEP, SEP, VEP Additional channels, e.g. EOG, can be calculated using all electrodes and displayed along with the current montage FFT over marked block, or mean, moving FFT over whole EEG or longer epochs. Whole head maps (3D and 2D) of spectral power, amplitude, and phase DSA trend analysis using standard brain source montages or the current, user-defined montage Automatic detection, definition, display, and correction of eye and EKG artifacts Optimized separation of artifacts and EEG activity during review and automatic paging Optional user defined correction of artifacts based on template pattern search and averaging ERP analysis and averaging (optional) EEGFocus provides off-line averaging and analysis of evoked and event-related potentials (ERP). Triggers from external stimulators or created internally, e.g. from rectified EMG, are defined along with specific conditions in paradigm scripts. Using a predefined protocol, ERP averages can be obtained rapidly using a fast 2-dimensional artifact scan to define noisy channels and epochs. Definition of triggers, experimental variables, and conditions in paradigm script Fast averaging of all conditions with split half option, e.g. alternating buffers Top view display of the averaged ERPs with overplot option for multiple conditions Automated peak detection and many user-definable display options |
