We introduce the concept of a new approach to bioelectrical mapping by measuring and imaging the higher-order spatial derivative of the electrical potential over a surface. Computer simulation studies have been conducted to test the feasibility of this approach. The present computer simulation results suggest that the surface distribution of the higher-order spatial derivative of the potential may provide a preferable means in localizing spatially separated bioelectrical sources. The higher-order derivative mapping appears to provide another important alternative approach to mapping underlying bioelectrical activity in the heart, brain and other organs.
