Abstract

Disclosed are methods and systems for optimized deep or superficial deep-brain stimulation using multiple therapeutic modalities impacting one or multiple points in a neural circuit to produce Long-Term Potentiation (LTP) or Long-Term Depression (LTD). Also disclosed are methods for treatment of clinical conditions and obtaining physiological impacts. Also disclosed are: methods and systems for Guided Feedback control of non-invasive deep brain or superficial neuromodulation; patterned neuromodulation, ancillary stimulation, treatment planning, focused shaped or steered ultrasound; methods and systems using intersecting ultrasound beams; non-invasive ultrasound-neuromodulation techniques to control the permeability of the blood-brain barrier; non-invasive neuromodulation of the spinal cord by ultrasound energy; methods and systems for non-invasive neuromodulation using ultrasound for evaluating the feasibility of neuromodulation treatment using non-ultrasound/ultrasound modalities; neuromodulation of the whole head, treatment of multiple conditions, and method and systems for neuromodulation using ultrasound delivered in sessions.

2. The method of claim 1 where the fixed-pulse pattern has a fixed pulse width and a fixed inter-pulse interval.

3. The method of claim 1 where the random pulse pattern is created with random pulses generated using a computer running a pseudo-random-number-generator program generating random numbers in the range of 1 to whatever the whole range of the target average pulse interval divided by the pulse width.

4. The method of claim 1 where the pattern generated by Fibonacci sequence used in the neuromodulation is determined by a Fibonacci sequence applied to the number of space elements between pulse elements.

5. The method of claim 1 where the pattern is a continuous level that may vary in amplitude.

6. The method of claim 1 where the pattern consists of bursts containing any pulse pattern train and includes use of bang-bang mode.

7. The method of claim 1 where a multiple-frequency amplitude modulation pattern is created by superimposing two or more different amplitude modulated frequencies on the carrier frequency where frequencies will be in the range of approximately 10 Hz to 400 Hz for down regulation and approximately 500 Hz to 2 MHz for up regulation.

8. The method of claim 1 where the pattern is created by sweeping the amplitude-modulated neuromodulation frequency through a range between approximately 10 Hz to 400 Hz for down regulation and approximately 500 Hz to 2 MHz for up regulation.
