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

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
