... Transcranial pulsed ultrasound (TPU) uses low intensity, low frequency ultrasound (LILFU) as a method to stimulate the brain. In 2002, Dr. Alexander Bystritsky first proposed the idea that this methodology contained therapeutic benefits ...
... On Dec 26th, 2013, Dr Bystritsky (a Russian trained psychiatrist) was reprimanded by the Medical Board of California...
The overall average patient rating of Dr. Alexander Bystritsky is Below Average ... The rating is 2 out of 5 stars

SynSonix is a privately held company founded in 2009. SynSonix was originally founded by Dr. William Tyler of Arizona State University ... The foundation of SynSonix is its patented technology using pulsed ultrasound to noninvasively and remotely control brain function. SynSonix is focused on developing medical devices designed to noninvasively control brain function for diagnostic and therapeutic purposes for such diseases as epilepsy, chronic pain, traumatic brain injury, Alzheimer's, Parkinson's, depression, brain cancers, and obesity ...
How many cu$tomer$ in America for a non-invasive therapy which could, theoretically, address obesity ?. Who wouldn't want to invest in that technology, if it worked.
Could synthetic nanoparticles injections in the atmosphere provides a piezoelectric framework for brain-machine interfaces through ultrasonic transduction of brain waves into electrical signals?
neuromodulation modify brain activity?
QuoteCould synthetic nanoparticles injections in the atmosphere provides a piezoelectric framework for brain-machine interfaces through ultrasonic transduction of brain waves into electrical signals?To transfer power efficiently, you need:- a good impedance match between transducer and target.- a transducer that is at least a wavelength in size (they are promoting use of ultrasound at 5.7MHz).
Analyzing it:- There is a very poor impedance match between the air and body, which effectively blocks ultrasound.- The impedance match from air to the bone of your skull is even worse- I expect that there would be a very poor impedance match between synthetic nanoparticles and the air.- The "nanoparticles" would need to be at least 0.05mm across to produce any significant signal at 5.7MHz; this is quite a large dust particle, which would fall out of the air pretty quickly.- The battery in your smartphone goes flat after a day - think what will happen to the nanobattery in a high-power ultrasound transmitter!- To produce particular neurological results, you would need to target it to particular regions of the brain. You would need to provide the hypothetical nanodust with legs (like little nits).This is why the familiar baby ultrasound is mains-powered, typically uses a transducer at least 5mm across, is held in direct contact with the body, and uses an impedance-matching gel to improve power transfer.
What are you smoking?
I'm not sure what means "impedance match".
