Precise Estimation of Brain Electrical Sources Using Anatomically Constrained Area Source (ACAS) Localization

This paper proposes a new parametric method to estimate electrical sources more precisely. In the proposed method, only four free parameters need to be evaluated for each anatomically constrained area source (ACAS) in order to express both spatial extension and location of brain electrical activities on cortical surface. The feasibility of the model was verified through the application to realistic simulations and epilepsy patients' data
