The so-called neural dust, which the team implanted in the muscles and peripheral nerves of rats, is unique in that ultrasound is used both to power and read out the measurements. Ultrasound ...

Neural dust researchers have already shrunk them to a 1 millimeter cube – about the size of a large grain of sand – contain a piezoelectric crystal that converts ultrasound vibrations from outside the ...

Recently, Neural Analytics presented research data that demonstrated there was no statistical difference between ultrasound blood flow data collected with its NeuralBot™ System or data collected ...

The researchers discovered that ultrasound stimulation can modulate neural plasticity - the brain's ability to rewire itself - through the activation of key molecular pathways. Specifically ...

The ultrasound-stimulated nanoparticles then generate current for neural stimulation, resulting in the release of neurotransmitters. (Courtesy: Nat. Biomed. Eng. 10.1038/s41551-022-00965-4) Deep brain ...

It’s unclear exactly why ultrasound has this effect, but the findings suggest that studying the neural circuits involved in torpor could reveal ways to manipulate metabolism beyond the lab.

Beyond therapy, the technology may also aid drug testing by creating accurate neural models in labs. Future work could refine ultrasound parameters for optimal differentiation and scale the system ...
