“Polina Anikeeva’s team at MIT adopted a slightly different approach, using spherical iron oxide particles that give off heat when exposed to an alternating magnetic field.“

Two teams of scientists have developed new ways of stimulating neurons with nanoparticles, allowing them to activate brain cells remotely using light or magnetic fields. The new methods are quicker and far less invasive than other hi-tech methods available, so could be more suitable for potential new treatments for human diseases.
Researchers have various methods for manipulating brain cell activity, arguably the most powerful being optogenetics…
