Abstract
An important problem in Neuroscience is to determine the brain active regions given the measured electrical potentials on the scalp. This problem is called "the source localization problem". An accurate solution to this problem will provide an opportunity to access the active cortex region non-invasively. This knowledge can help neurologist in the treatment of epilepsy patients and can help psychologist to better understand the brain functions.
This problem is ill-posed in the sense that it has no unique solution and a priori knowledge that imposes constraints in selecting the solution is required. At the center of this problem is to have an accurate computational model of the human head as a volume conductor. This model predicts the measured electrical potentionals on the scalp given the current source, the geometry and the conductivities of the head tissues.
In this presentation I will talk about the computational environment we used at Neuroinformatic Center to determine the human head tissues conductivities non-invasively. Then I will open discussion about our objective to build a Problem Solving Environment that helps multi-disciplines to cooperate in solving this problem by studying the solution sensitivity to the models and parameters.
