Biocompatible microparticles remotely stimulate neural impulses in mice as safer alternative to brain electrodes
Researchers from Skoltech—a VEB.RF group institution—and their colleagues at the Institute of Cytology and Genetics of SB RAS and other medical science centers in Russia have managed to modulate the breathing and heart rate of a mouse by wirelessly stimulating its vagus nerve. The electrical stimulation was delivered by nontoxic magnetic microparticles, which acted as tiny electrodes in the nerve…
Researchers from Skoltech and the Institute of Cytology and Genetics have developed a promising alternative to brain electrodes for stimulating neural impulses in mice. By using nontoxic magnetic microparticles, they were able to remotely modulate the breathing and heart rate of a mouse. These biocompatible microparticles, made of polylactic acid and iron oxide, are smaller than existing electrodes and could be delivered via injection.
The team's innovative approach could potentially reduce the need for invasive brain implants, although further research is needed to establish efficacy in neurological disorders.
