SOURCE MONTAGES AND 3D WHOLE-HEAD MAPPING

New montage editor

  • Graphical editing of user montages for convenient data review
  • Virtual montages with standardized electrode locations
  • Combined montages of recorded, virtual, and source channels
  • 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

BESA 5.0 - 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

Frontal lobe source montage

Small frontal spikes become visible in this source montage because background activities in other brain regions are separated.
