Abstract
The determination of the sources of electric activity inside the brain from electric and magnetic measurements on the surface of the head is known to be an ill-posed problem. In this paper, a new algorithm which takes temporal a priori information mo deled by the smooth activation modell into account is described and compare d with existing algorithms such as Tikhonov-Phillips.
