1. A method of treating psychiatric, neurological and neuroendocrine disorders in a mammal, the method comprising the steps of: applying a focused ultrasound pulse (FUP) to a live neuronal circuit in a tissue of the mammal, and the applied FUP uses a variation in pulsation parameter frequency to disrupt or activate a neuronal circuit function such that a naturally occurring hormone is released in the live neuronal circuit and in an organ connected to the live neuronal circuit and a level of the naturally occurring hormone is modulated; and monitoring a tissue image including the live neuronal circuit from an imaging system during the application of the FUP.
