This powerful new state of the art 3-Dimensional Electrical Neuroimaging tool uses a real-MRI with 12,270 voxels; the Boundary Element Method (to compute the inverse solution to avoid the errors inherent in the use of a spherical head model, allowing for more accurate source localization at depths); and swLORETA (adjusts for source space inhomogeneity and provides accurate estimates of source gradients from the upper to the lower cortical layers). The NeuroNavigator with Raw Current Density values must be purchased before you can have access to the Real-Time NeuroNavigator and the NeuroNavigator Time Domain Capture Tools in NeuroGuide or before purchasing any of the NeuroNavigator add-on options.
