Credit: SciTechDaily.comFunctional ultrasound (fUS) marks a substantial leap in Brain-Machine Interface technology, providing a less invasive technique for accurate control of electronic gadgets by interpreting brain activity.Brain– device interfaces (BMIs) are gadgets that can read brain activity and equate that activity to control an electronic gadget like a prosthetic arm or computer system cursor. In 2021, Caltech researchers established a method to read brain activity utilizing functional ultrasound (fUS), a much less invasive technique.Functional Ultrasound: A Game Changer for BMIsNow, a new research study is a proof-of-concept that fUS technology can be the basis for an “online” BMI– one that checks out brain activity, analyzes its significance with decoders configured with device knowing, and subsequently manages a computer that can accurately predict movement with extremely minimal hold-up time.Ultrasound is utilized to image two-dimensional sheets of the brain, which can then be stacked together to develop a 3-D image. The work was a cooperation with the lab of Mickael Tanter, director of physics for medicine at INSERM in Paris, France.Advantages of Functional Ultrasound”Functional ultrasound is a completely new technique to include to the toolbox of brain– machine interfaces that can assist people with paralysis,” states Andersen. “While electrodes can really specifically measure the activity of single neurons, they require implantation into the brain itself and are tough to scale to more than a couple of small brain regions. In this research study, the researchers used ultrasound to determine modifications in blood circulation to particular brain regions.
