| ASA source analysis |
Source reconstruction in asa ASA offers an extensive selection of neuroimaging methods for EEG and MEG analysis. Source modeling has advanced from single dipole solutions to LORETA, MUSIC and minimum norm estimates - and ASA supports all of these. Moreover, realistic head modeling using boundary elements can be applied irrespective of what particular source modeling approach is used. MRI based individually shaped head models can be interactively generated and provide more accurate solutions. |  |
From signals to sources ASA let's you apply source reconstruction methods within the regular workflow of your signal processing. All you need is good data! You load an individual head model or the standard model that is installed with ASA, electrode positions, and MRI, then specify the time interval for analysis, and run the source analysis that suits your ideas around this particular brain activation. |  |
Integration of MRI Individual MRI can be imported from DICOM files and is further processed for head and source modeling. The data are coregistered on the basis of anatomical landmarks. ASA provides interactive tools for the 3D image segmentation and head modeling, as well as a transformation from individual coordinates to standard Talairach coordinates. |  |
Cortical imaging of distributed activity The complexity of brain activity varties greatly, thus our mathematical modeling has to allow a sufficient degree of freedom to explain the measured data. ASA offers a representative set of methods for focal and distributed source modeling. Your results can be exported for further processing. The highly configurable 3D displays let you freely rotate and zoom into your results. |  |
