Visualization of Contrast Maps on Brain Views
The Brain Window shows results of incremental statistical data analysis as overlays - like a movie - on various display formats called views. The primary view is the Multi-Slice View which is always shown first after starting real-time analysis provides a good overview of the brain data and overlayed statistical results. To inspect details at the voxel level, the Single-Slice View is most appropriate. A three-dimensional orientation in space is provided by the Volume View. While the Volume View shows the data in three orthographic views in the original slice space, the Anatomical Volume View allows to show the statistical data in a more abstract high-resolution 3D space, such as AC-PC or Talairach space. The Surface View provides advanced visualization of the statistical data on previously reconstructed cortex mesh representations.
The displayed contrast maps are automatically updated after each data point has been obtained and processed using a recursive least squares General Linear Model (RLS GLM). A "data point" here refers to one measurement of all functional slices and is also called a (functional) volume. The number of the currently processed data point can be inspected in the Information Window together with the elapsed time from the start of the processed run.
