rTMS at harmonics of biological signals
Repetitive Transcranial Magnetic Stimulation (rTMS) is administered at a pulse rate that is equal to or a harmonic of a biological metric of a patient. The purpose is to provide frequency coupling among different organs (e.g., heart, brain, breathing, and gastrointestinal movement) through rhythmic entrainment. The specific harmonic chosen is the one closest to a desired EEG frequency. The desired EEG frequency is chosen based on the cognitive element or symptom that is targeted.
1. A method of modulating a brain activity of a mammal wherein said method comprises subjecting the mammal to repetitive transcranial magnetic stimulation (rTMS) at a frequency of a non-EEG biological metric, or a harmonic or sub-harmonic of said non-EEG biological metric, for a time sufficient to modulate said brain activity and wherein an improvement in a physiological condition or a neuropsychiatric condition is achieved.
2. The method of claim 1 wherein the biological metric is heart rate, respiratory rate, or gastrointestinal movement rate.
3. The method of claim 1 wherein the brain activity is a desired EEG band and the rTMS frequency is equal to, or a harmonic or sub-harmonic of, a non-EEG biological metric that is closest to the targeted frequency in the desired EEG band.
4. The method of claim 3 wherein the non-EEG biological metric is heart rate.
5. The method of claim 1 wherein the physiological condition is concentration, sleep, alertness, memory, blood pressure, stress, libido, speech, motor function, physical performance, cognitive function, intelligence, height or weight.
6. The method of claim 1 wherein the neuropsychiatric condition is Autism Spectrum Disorder (ASD), Alzheimer's disease, ADHD, schizophrenia, anxiety, depression, coma, Parkinson's disease, substance abuse, bipolar disorder, a sleep disorder, an eating disorder, tinnitus, traumatic brain injury, post-traumatic stress syndrome, or fibromyalgia.
7. The method of claim 2 wherein the frequency is delta band (<4 Hz), theta band (4-8 Hz), alpha band (8-13 Hz), beta band (13-30 Hz), gamma band (˜40 Hz) or Mu band (8-13 Hz).
8. A method of modulating a brain activity of a patient having Alzheimer's disease, wherein said method comprises subjecting the patient to repetitive transcranial magnetic stimulation (rTMS) at a frequency of a non-EEG biological metric, or a harmonic of said non-EEG biological metric, for a time sufficient to modulate said brain activity wherein an improvement in the symptoms of the Alzheimer's disease is achieved.
9. The method of claim 8 wherein the biological metric is the patient's resting heart rate.
10. A method of modulating a brain activity of a patient having chronic pain, wherein said method comprises subjecting the patient to repetitive transcranial magnetic stimulation (rTMS) at a frequency of a non-EEG biological metric, or a harmonic of said non-EEG biological metric, for a time sufficient to modulate said brain activity wherein an improvement in chronic pain is achieved.
11. The method of claim 10 wherein the biological metric is the patient's resting heart rate.
