Summary:

- This article discusses the use of magnetic nanodiscs to stimulate the brain, which could lead to new non-invasive treatments for neurological and psychiatric disorders.
- The nanodiscs are made of iron oxide and can be remotely controlled using magnetic fields, allowing for targeted stimulation of specific brain regions.
- Preliminary studies in mice have shown the nanodiscs can be used to modulate neural activity and behavior, suggesting this technology has potential for therapeutic applications.
