This powerful new state of the art 3-Dimensional Electrical Neuroimaging software tool uses a real-MRI with 12,270 voxels and the Boundary Element Method (BEM) to compute the inverse solution. The BEM avoids the errors inherent in the use of a spherical head model, this allows for accurate source localization at depths. In addition, the NeuroNavigator™ add-on uses swLORETA (weighted sLORETA) that adjusts for source space inhomogeneity and provides accurate estimates of source gradients from the upper cortical layers I – III to the lower cortical layers IV-VI. NeuroNavigator with Raw Current Density (CSD) values must be purchased before you can purchase any of the NeuroNavigator™ add-on options (i.e., Z scores of CSD norms; Coherence and Phase or Effective Connectivity (Phase Slope Index) and/or Diffusion Tensor Imaging.
