Abstract
We study the sensitivity with respect to an uncertain conductivity in the electroencephalography (EEG) forward problem. A three layer spherical head model with different and random layer conductivities is considered. The randomness is modeled by Legendre Polynomial Chaos. We introduce a (regional) sensitivity index to quantify the sensitivity of sensors with regard to subregions of the brain. As an example the cerebrum and cerebellum are compared together with the whole head as reference.
