From raw data to a publication-ready figure

The graphical interface covers electrode montages, spatial and temporal filter design, artefact handling, quality control, spectral analysis, coherence and correlation, bandpower, ERD/ERS, EP analysis and visualisation in over 100 functions. Extracted features go straight into linear and non-linear classifiers; your preferred processing steps are saved as a script and applied to several data sets in batch mode.

From coherence to P300 accuracy

The EEG toolbox holds coherence and event-related coherence, ERD/ERS time-frequency maps (bootstrap, complex demodulation, wavelet, Hilbert), common spatial patterns (CSP), the phase locking value (PLV) and EP calculations such as ASSR, MMN, BAEP, P300 and N400. Hjorth and Barlow parameters, sliding fractal dimension, minimum energy for SSVEP/SSSEP and P300 BCI accuracy analysis are included too. The high-resolution EEG toolbox maps activity onto realistic head models built from CT and MR data.

ECG, CFM, CCEP, ECoG and spikes

The ECG toolbox calculates QRS detection and HRV parameters, Poincaré plots and event-related ECG changes. Cerebral function analysis offers aEEG (CFM) with automatic segmentation for neonatal and preterm brain function. The CCEP and ECoG toolboxes focus on cortical connectivity and high-gamma analysis in intracranial recordings; the spike toolbox calculates firing rates, PSTHs, the Skaggs index and spatial coherence.
