Source montages

Source montages and 3D whole-head mapping

Graphical display of a user-defined montage

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

User-defined 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

Virtual montages

• Reference Free
• 10-10 Average
• CSD-Laplacian
• Double Banana
• Triple Banana
• Horizontal Bipolar
• A1/A2 Reference
• Combined Ears
• Referential
• Reference Free (10-10)
• CSD-Laplacian (10-10)

Source montages

• Source montages for optimally reflecting:
  • Frontal Region
  • Central Region
  • Parietal Region
  • Temporal Region
  • Evoked Potentials (AEP, VEP, SEP)
• Source montages for swiftly analyzing resting state data
  • Default mode network
  • Fronto-parietal task control network
  • Dorsal attention network
  • Ventral attention network

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
