DARPA and NIH-Funded ‘Neuroengineers’ Create ‘Wireless Technology to Remotely Activate Specific Brain Circuits’ Using Magnetic Fields and Nanoparticles

A team of scientists led by Rice University “neuroengineers” has created wireless technology to “remotely activate specific brain circuits” on the sub-second timescale. To demonstrate the capability, the neuroengineers used magnetic fields to “activate targeted neurons that controlled the body position of freely moving fruit flies in an enclosure.” The scientists say this research furthers the drive toward the “holy grail of neurotechnologies”: remote control of select neural circuits with magnetic fields.

Incredibly, this use of magnetic fields to control select brain circuits remotely is not new technology. The technique is referred to as “magnetogenetics” and this particular demonstration—outlined in Nature Materials—mainly aims to demonstrate “precise temporal modulation of neural activity” on sub-second timescales as well as “stimulation of different groups of neurons” using varying digital signals.

Previously, the neuroengineers note in their paper, in vivo (in the body) response time of thermal magnetogenetics was on the order of tens of seconds, and was not able to stimulate different groups of neurons.
