Scientists Developed Magnetic Nanoparticles that can Remotely Modulate Neural Circuits

Currently, neuroscience researchers rely heavily on invasive procedures to stimulate and record the neural activity of experimental animals. A team of MIT scientists has constructed a type of heat-sensitive, magnetic nanoparticle that can deliver chemical stimulants deep into brain tissues and release them on demand, providing a new means to remotely modulate the behaviors of test subjects.
