A method and an apparatus for the electromagnetic modification of brain activity, in particular for the model-based controlled or regulated, respectively, electromagnetic modification of brain activity in vivo, as well as to the resulting modification of behavior is disclosed. A brain activity model (which describes the influence of exogenous electric and/or magnetic fields on a brain activity) is used, and a behavioral model (which describes the correspondence between brain activity and behavior) is used. Thereby it becomes possible, for the first time ever, to influence the behavior of a person by means of exogenous input in a controlled way. Intra-individual and/or time-dependent non-observables, as well as to determining individual, is provided, if necessary intra-individual and/or time-dependent translation operators from extracranial signal to control force, whereby a secure and controlled intervention as part of a open or closed control loop is created, which in turn results in achieving a brain activity target in a reliable way. Using a behavioral model ensures that achieving a brain activity target corresponds to achieving the individual behavioral target of the user.
