In Brief
- Needle-thin implant records, delivers drugs, and stimulates brain regions simultaneously.
- Offers a precise, less invasive method to study brain activity and disorders.
- Successful tests conducted in mice demonstrate functional viability.
- Potential future use includes treatment for neurological disorders like epilepsy.
Scientists have created a highly flexible, needle-thin brain implant known as mAxialtrode that can perform three functions at once: recording neural activity, delivering drugs, and stimulating various brain regions. This multifunctional device was successfully tested on mice, suggesting it could provide scientists with a more precise and less invasive way to explore brain functions.
The innovative implant integrates electrical recording, optical stimulation, and fluid delivery capabilities within a single flexible fiber. Researchers believe this advancement will improve understanding of neural circuits and support development of more effective treatments for neurological disorders.
According to the study, this implant's flexibility reduces tissue damage and scarring compared to traditional rigid implants. The multifunctional approach enables simultaneous monitoring and manipulation of brain activity, offering significant advantages for research and therapeutic applications.
Future potential includes treatment for conditions such as epilepsy by delivering drugs directly to targeted brain areas while monitoring the neural response in real time.
