Ultrasound examination is not only a diagnostic method for imaging human organs and systems. It can be used as a method of focused treatment of mood disorders. The use of ultrasound as a therapeutic agent depends on the frequency parameters and the type of equipment. In addition, ultrasound facilitates the delivery of a drug across the blood- brain barrier to specific brain structures.
Thus, ultrasound can be one of the means of neurostimulation .
The use of low-intensity and low-frequency ultrasound as a stimulator of neural networks ultimately leads to the activation of neurons through the influence on the sodium- calcium channels of the cell membrane. ( Tyler with et al , 2008).
Other possibilities and ways of achieving a similar effect in a non-invasive way remain problematic.
