Scientists at Rice University have developed an incredibly tiny implantable device that can stimulate the brain. This pea-sized device is called the Digitally programmable Over-brain Therapeutic, or DOT.
Unlike other implants, this device doesn't need batteries! It wirelessly receives power from an external transmitter using a special material that converts magnetic fields into electricity.
The DOT could significantly improve treatment for disorders like depression by directly stimulating the brain. It's much less invasive than current options and can potentially be controlled at home by the patient.
The DOT has successfully stimulated a human patient's motor cortex (the brain region controlling movement). It has also been shown to work safely in animal studies.
Researchers aim to use the DOT for treating various brain areas and want to explore networks of these implants for personalized therapy. Motif Neurotech is working on getting FDA approval for human trials, and interested people can sign up on their website.
The study is published in the journal Science Advances.
