This approach can produce an estimate of the neural activity at any location by changing the location r dip . It assumes that any source can be explained as a weighted combination of dipoles. Hence the geometry of sources is not restricted to points but may be distributed in nature according to the variance values. Moreover, this approach does not require prior knowledge of the number of sources and anatomical information is easily included by evaluating Va^r(r dip ) only at physically realistic source locations.
