1. A method for stimulation of target neural tissue with a system including a biocompatible shaft having distal and proximal ends and a longitudinal axis and defining a hollow therein, the method comprising: forming at least one microcoil system that includes a corresponding microcoil characterized by a microcoil axis and that is equipped with a metallic shield element extending along and adjacent to a loop of said microcoil, said forming including juxtaposing said metallic shield element substantially tangentially parallel to a surface defined by said microcoil; defining an electrical terminal for said at least one microcoil system to receive an electrical waveform from a power source; defining a first angle based on at least one stereotactic mark associated with a target neural tissue and a second angle describing an orientation of the longitudinal axis with respect to said at least one stereotactic mark to provide, in operation of said at least one microcoil that has been activated by an electromagnetic input applied externally thereto, activation of a neuron having a predetermined orientation in said target neural tissue; and disposing said at least one microcoil system within the hollow that is electrically and fluidly insulated from an ambient medium surrounding the shaft to orient the microcoil axis at the first angle with respect to the longitudinal axis.
