Why Purchase the NeuroNavigator

Improved Localization Accuracy:

  • NeuroNavigator uses a real MRI with 12,470 voxels. This is the largest number of voxels than any other EEG inverse solution.

  • NeuroNavigator uses a realistic head model based on the surfaces and voxels of a real MRI with exquisite detail.

  • NeuroNavigator uses a Boundary Element Method (BEM) to compute the inverse solution and not a spherical head model that does not fit the boundaries of the brain.

  • NeuroNavigator uses swLORETA (weighted sLORETA) that resolves depth of sources in the cortex.

  • NeuroNavigator uses Single Value Decomposition (SVD) to transform the heterogenous Lead Field into a Homogeneous Lead field that not only improves localization accuracy but also resolves sources at depths of the cortex.

  • NeuroNavigator uses a Symptom Check List and Specific Network Hubs (Brodmann areas) so that users can link the brain to dysregulation in networks related to symptoms.

  • NeuroNavigator computes Z Scores and Raw values including Coherence and Phase Differences and Effeective Connectivity (magnitude and direction of information flow using the Phase Slope Index).

  • Measure the Scalp Electrical Field + Cortical Sources + Functional Connectivity + Effective Connectivity + Diffusion Tensor Imaging Simultaneously using Transparent Scalp, Skull and Brain controls.

  • NeuroNavigator is user friendly and allows one to rapdily change views and slices and a cutting tool to explore dysregulated brain regions linked to symptoms.

  • Saves time in linking a Patient/Client's symptoms to dysregulation in Brodmann areas' nodes and connections between nodes to produce a tailored Neurofeedback protocol that can be used inside of NeuroGuide.


Advanced Navigation and Cutting Tools:

  • The easy to use cutting tools allow one to slice through the MRI volume and EEG Currents and Z scores in the Sagital, Coronal and Axial planes.

  • Clinicians can view quatrant voumes in 3-dimensions of EEG currents and Z scores.

  • Change transparency in slices and the volume to view different surfaces.

  • Navigate inside of slices or volumes and view the Z scores and currents for a given Brodmann area.

  • Navigate inside of different networks linked to symptoms.

  • Clinicians can easily print and/or save the slices and voumes.

Import High Density EEG Recordings:

  • The Key Institute LORETA and sLORETA are limited to 19 channels of EEG.  NeuroNavigator has the abilitly to use files with 32, 64, 128 and 256 channels!

  • Compare changes in the source localization accuracy as one increases the number of scalp EEG sensors.

  • Change transparency in slices and the volume to view different surfaces.
