SOURCE MONTAGES AND 3D WHOLE-HEAD MAPPING
Montage editor
- Graphical editing of user montages for convenient data review
- Virtual montages with user-definable or standardized electrode locations
- Computation of arbitrary arithmetic combinations of channels
- Remontaging to arbitrary channel averages (e.g. ears, mastoids, user-defined)
- Immediate resorting for regional and hemispheric comparison
Source montages
- Transformation of surface EEG or MEG into brain source activity
- Montages derived from multiple dipole or regional source models
- Standardization for various brain regions or definition by the user
- Additional channels to display PCA components and / or eye artifacts
3D whole-head mapping
- Whole-head spline interpolation for voltage and CSD mapping
- 3D or 2D view of maps, sensors, and head surface points
- Mapping of FFT power, amplitude, and phase
- MEG maps of flux and planar gradients at the scalp surface
- Time series of maps with easy selection of viewpoint, number of maps, and epoch of interest
Montage Editor
User montages can be easily defined in the graphical montage editor. Source montages are visualized in a standard head.
Frontal lobe source montage
Small frontal spikes become visible in this source montage because background activities in other brain regions are separated.
