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
