Researchers have developed a new type of brain implant that requires no surgeryThe microscopic chips are injected into the arm and travel to a specific part of the brain through the bloodstreamOnce there, they self-implant and provide electrical stimulation to treat brain disorders

MONDAY, Nov. 10, 2025 (HealthDay News) — Imagine a brain implant that could be placed without surgically opening a person’s skull, but instead through a simple injection in the arm.

Massachusetts Intitute of Technology researchers are working on microscopic, wireless electronic chips that can travel through the bloodstream and self-implant in a targeted region of the brain.

In a study with lab mice, the team found that the chips — each one-billionth the length of a grain of rice — can indeed id
