- The montage planner compares 5,124 cortical sources and reports median errors from about 0.5 cm at 64 channels to 3.5 cm at eight.
Field notes
The Brain Source Map simulates cortical activity on FreeSurfer fsaverage, projects it through a three-shell head model to as many as 128 electrodes, then reconstructs sources using MNE, dSPM, sLORETA, and eLORETA. Its montage planner compares estimates across 5,124 cortical sources under simulated noise; the page gives median errors of about 0.5 cm at 64 channels and 3.5 cm at eight.
