Transcranial Focused Ultrasound Stimulation of Periaqueductal Gray for Analgesia
IEEE Transactions on Biomedical Engineering, 2022Transcranial focused ultrasound (tFUS) is regarded as a promising non-invasive stimulation tool for modulating brain circuits. The aim of this study is to explore the feasibility of tFUS stimulation for analgesia applications.50 µl of 3% formalin solution was injected into the rat's left hindpaw to build a pain model, and then the local field potential

Acupoint stimulation device using focused ultrasound
2010 Annual International Conference of the IEEE Engineering in Medicine and Biology, 2010Acupuncture is used widely in oriental medicine. But it is difficult to stimulate continuously or intermittently in daily life with conventional acupuncture. An acupoint stimulation device using focused ultrasound has been developed. Because the device size is about 6 mm in diameter, it can be easily put on the skin during daily life.

Vibrotactile feeling induced by focused ultrasound stimulation
2014 11th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2014Utrasound stimulation has been regarded as the promising method for haptic engineering. As the first step for the successful implementation of this technique, vibrotactile feeling induced by focused ultrasound stimulation is studied in this paper. Experiments about radiation force and vibrotactile feeling were conducted, and the results buttress the ...

Skull Impact on the Ultrasound Beam Profile of Transcranial Focused Ultrasound Stimulation
2019 41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019Transcranial focused ultrasound stimulation (tFUS) is a promising noninvasive neuromodulation tool for targeting brain regions with millimeter-scale spatial resolutions. In conventional tFUS studies, a focused ultrasound beam generated by an external ultrasound transducer is delivered to the neural target.

Numerical Evaluation of the Human Skull with Focused Ultrasound Stimulation
Acoustics Australia, 2023Transcranial focused ultrasound stimulation is a promising brain stimulation technique for its noninvasiveness and higher spatial resolutions and is used for various neuromodulation applications. As the skull is the primary barrier to delivering ultrasound to the deep brain region, it induces unpredictable ultrasound exposure.

Brief Effect of Acupoint Stimulation Using Focused Ultrasound
The Journal of Alternative and Complementary Medicine, 2013Acupuncture is used worldwide in medical treatment. However, needle insertion damages the skin and patients sometimes feel pain. To avoid such drawbacks, an acupoint stimulation device using focused ultrasound has been developed. Ultrasound stimulation does not damage the skin like acupuncture does because ultrasound can deliver vibration energy to ...

Use of focused ultrasound for stimulation of nerve structures
Ultrasonics, 1984Pulsed focused ultrasound can stimulate the receptor and conductive nerve structures of humans and animals as well as the neurons of the central nervous system of invertebrates. The possibility of a wide practical use of this method in medicine and physiology is considered.

Focused ultrasound facilitated adenoviral delivery for optogenetic stimulation
2015 IEEE International Ultrasonics Symposium (IUS), 2015Optogenetics is a recently developed technique that has been widely implemented in the field of neuroscience. Channelrhodopsins (ChR), i.e., proteins that function as optically activated ion channels, are introduced into neurons either by viral transduction or transgenic manipulations.

A Prototype Stimulator System for Noninvasive Low Intensity Focused Ultrasound Delivery
2012A prototype Low Intensity Focused Ultrasound (LIFU) stimulator system was developed to evaluate non-invasive neuromodulation in a large animal model. We conducted a feasibility study on a Göttingen minipig, demonstrating reversible, targeted transcranial neuromodulation. The hypothalamus of the minipig was repeatedly stimulated with LIFU which
