Anatomy of the headMarch 5th 2009
Goal: construct a geometrical model of the head for inverse problem
1. seed the sources in the grey matter according to pyramidal hypothesis of EEG
2. model tissues that contribute to changes in the propagation of the signal
Overview of the tissues
Muscles
Muscles
skull
skull
skull
Vascular system
Frontal sinuses
CSF
Constraint 1:
Seeding the sources in the grey matter, with their proper 3D orientation
Issues: resolution, outer and inner boundary crossing, etc…
Constraint 2: compartmental or voxel-based anisotropy
Constraint 2: compartmental or voxel-based anisotropy
