Abstract

An rTMS coil or set of coils are designed to affect multiple regions of the brain with synchronous magnetic field pulses. Multiple coils aligned over the targeted regions of interest, or a single coil that is stretched or enlarged in a shape that allows the magnetic field to affect the areas of interest are disclosed. Also disclosed is a method of optimizing repetitive transcranial magnetic stimulation (rTMS) treatments.

Claims

1. A repetitive transcranial magnet stimulation (rTMS) device for treating a neuropsychiatric condition or to improve a physiological function, the rTMS device comprising:

a coil configuration that produces a magnetic field capable of delivering magnetic stimulation, at an rTMS pulse frequency, to two or more regions of a brain of a patient fitted with the rTMS device,

wherein the rTMS device is configured to analyze recorded signals from the patient and determine, based on the recoded signals, a harmonic or subharmonic of a non-EEG biological metric of the patient,

wherein the rTMS pulse frequency is the harmonic or subharmonic of the non-EEG biological metric,

wherein pulses generated by the coil configuration are synchronized and promote coherence and synchronous behavior between multiple locations in the brain,

wherein the coil configuration comprises 2 or more coils, and

wherein each respective coil comprises an on/off switch.

2. The rTMS device of claim 1, wherein a geometry of the coil configuration is a phased-array of magnetic field emitting devices, allowing complex geometries and emission fields.

3. The rTMS device of claim 1, wherein the device is configured to deliver magnetic stimulation to the front and rear regions of the brain.

4. The rTMS device of claim 1, wherein the device is configured to deliver magnetic stimulation to the motor cortex and frontal cortex regions of the brain.

5. The rTMS device of claim 1, wherein the device is configured to deliver magnetic stimulation to the lateral sides of the frontal lobe region of the brain.

6. The rTMS device of claim 1, further comprising a recording device for recording the recorded signals from the patient.
