MIT researchers develop magnetic nanodiscs for less invasive deep brain stimulation therapy, modulating neuron activity in mice.

MIT researchers have created magnetic nanodiscs, about 250 nanometers in size, that could revolutionize deep brain stimulation therapy. These nanodiscs can be injected into the brain and activated by an external magnetic field, offering a less invasive alternative to current electrode implants. Initial tests in mice show they effectively modulate neuron activity, suggesting potential applications for treating neurological conditions like Parkinson's disease. Further research is needed for human use.
