A highly efficient Transcranial Magnetic Simulation (TMS) device. TMS is a non-invasive technique for researching different brain regions and possibly the treatment of some brain disorders. Existing TMS techniques make use of a unidirectional magnet limiting the stimulation to specific regions. This technology is based on a scanning magnetic field and on the understanding of the relationship of directionality, rise time and cooperatively of neurons in a network, and it offers the opportunity to construct a robust and efficient new TMS device.


Applications



  • Precise control of the brain areas that are stimulated.

  • Therapeutic treatments for depression, migraine and other mental disorders.

  • An accurate diagnostic tool for neurologist and neural surgeons.


Advantages



  • Accessing areas in the brain that currently area not responsive to TMS.

  • Modification to a well established technique.

  • Requires less voltage.

  • Easy excitation of in vivo model systems such as rats and in vitro ones such as neuronal cultures.


Technology's Essence


The theory behind this technology involves the understanding that neural response is direction dependent. Neurons whose axons are parallel to the magnetic field will be most significantly stimulated. Additionally, factors of magnetic field, rise time and neural cooperatively play a role. All these are addressed by a rotating magnetic field creating anisotropy of angles that match the neurons' orientation and the excitation of dendrites by applying pulses of the order of 1ms. This solution offers greater control over the TMS system.
