Abstract
A new technique for computing the potentials on the surface of a Boundary Element Method (BEM) model, the Lead Field Analysis (LFA) Algorithm, is described. It is based on the Reciprocity Theorem and is more computationally efficient, requires less storage space, and yields potentially higher accuracy for surface potential computations than the standard method currently in use
