Abstract
An improved apparatus is provided for transcranial magnetic stimulation in a brain of a subject. The apparatus is comprised of: a plurality of coils electrically connected in series to each other; and a single source of current electrically coupled to one of the plurality of coils. Each coil may include one or more windings of similar dimensions although the size of the windings varies between coils. Each of the coils is further dimensioned to stimulate brain tissue at a given distance while minimizing volume of the brain tissue excited by the magnetic field. During operation, the current source injects time varying current into the coils to create a magnetic field which in turn induces electric fields and eddy-currents inside the brain tissue of the subject.
