Mechanisms of Stimulation Effects of Focused Ultrasound on Neural Structures: Role of Nonlinear Effects
نویسندگان
چکیده
The feasibility of the use of short pulses or amplitude modulation of focused ultrasound for noninvasive local stimulation of superficial and deep-seated neural structures of humans to induce different somatic (tactile, warmth, cold, pain, etc.), and hearing sensations is discussed. Such possibilities are of interest for the application of this method in the diagnosis of neurological, dermatological, hearing and other diseases and disorders involving changes in perception of different sensations. We have investigated the main factors responsible for the stimulation effects of focused ultrasound. The results of the work show that nonlinear effects play an important role in the mechanisms of the stimulation effects of focused ultrasound on neural structures.

Review Paper: A Review on Brain Stimulation Using Low Intensity Focused Ultrasound
Brain stimulation techniques are important in both basic and clinical studies. Majority of well-known brain stimulating techniques have low spatial resolution or entail invasive processes. Low intensity focused ultrasound (LIFU) seems to be a proper candidate for dealing with such deficiencies. This review recapitulates studies which explored the effects of LIFU on brain str...

Background: Recently, ultrasonic neuromodulation research has been an important and interesting issue. Ultrasonic neuromodulation is possible by the use of low-intensity transcranial focused ultrasound (tFUS) to stimulate or inhibit the neural structures. The primary capability of this method is the improvement in the treatment progress of certain neurological and psychiatric disorders noninvas...
