  • Abstract
    A three-sphere model is used to investigate the effects of inhomogeneities introduced by the scalp and the skull on the apparent location and magnitude of a current dipole representing local activity in the brain. The magnitude of the dipole is found to decrease by a proportion of 40 percent, whereas the location of the dipole appears 35 percent more centric.
