Disclosed are methods and systems and methods for non-invasive neuromodulation using ultrasound to treat Traumatic Brain Injury including Concussion, Compulsive Sexual Behavior (sometimes called Compulsive Sexual Disorder), meningitis, and also provide for the elicitation of emotional catharsis. The neuromodulation can produce acute or long-term effects. The latter occur through Long-Term Depression (LTD) and Long-Term Potentiation (LTP) via training Included is control of direction of the energy emission, intensity, frequency, pulse duration, pulse pattern, and phase/intensity relationships to targeting and accomplishing up regulation and/or down regulation. Use of ultrasound neuromodulation in sessions can enhance the effects.
